By putting some tweets on a schedule, you can maintain an aura of activity with your twitter account even when you are on vacation or dealing with other matters. The convinience factor of even ‘canned’ tweets is enormous.

You can set tweets to be tweeted an a set time schedule of every three hours or what ever time factor you determine. Or better yet, simply set them up to be tweeted on a random schedule of say 63 minutes to 188 minutes. With a random time delay schedule your profile will surely appear to have normal activity. This is especially true if you write your tweets properly.

You can write your tweets to tell a story and show a progression of events or updates on special deals and any number of variations. The key is to make them appear natural, real and fitting to the time flow.

With tweet adder you can also limit the number of posts per day. This can be helpful if you load up your program every day. Then you can set up your schedule to start when you normally log in and then post tweets within your randon time delay with your desired maximum per day.

Your tweets can also include symbols which are very easy to add to the tweet from the symbol icon. Another nice option is the ability to keep all of your tweets and cycle through them again. This means that if you start with enough tweets in the beginning that you will never have to write another tweet for that profile again.

To help you creating tweets, tweet adder also has a tweet writer feature that will spin your basic tweet into many variations. You can also import tweets from any text file. These options make it much more simple to set up tweet adder once as a ‘set and forget’ program.

Also, if you create your tweets manually with a speadsheet you can easily cut and past one or two words to make slight changes on the tweets. You can create hundreds of them quickly. Then it is a simple matter to copy them into a text file and import them into tweet adder. With tweet adder you can just click the randomize icon and your prewritten tweets will be mixed up in a random fashion,

With all of these features and options it is a simple matter to have your twitter profile tweet on auto pilot indefinitely.

Other services like social oomph, tweet attack and hootsuite also let you schedule your tweets, but I prefer the ease, simplictiy and options that you get with tweet adder

Hootsuite and ping.fm are my duo secret weapon number 3.

I actually found pingfm first. As I was busy adding all my social network accounts to pingfm I saw their Hootsuite link. I was literally thrilled to found this combination. Not only did I marvel at the cabability of ping, I was positively awed by the possibilities of using them together.

First of all - with a single post in pingfm, the post will simultaneously be sent to major social networks like Facebook, YouTube, Twitter, MySpace, Flickr, LinkedIn, Last.fm, Digg, Classmates.com, Friendster, hi5, Stumble Upon, OkCupid, Match.com, 43 Things, Bebo, Plaxo myYearbook, wayn.com, Yahoo Personals, Orkut, Tagged.com, Reunion.com, Plurk, Ning, Pogo.com, Shelfari, fubar, Adult Friend Finder, Plenty of Fish.com, Xanga, Plaxo Pulse, PalTalk, Friends Reunited, Multiply.com, tumblr.com, Ping.fm, Fitness Singles.com, Pix.ie, mycountryspace, BlackPlanet, mylife.com, ZooLoo, craftynation, Essembly, Chatterbox, schülervz, www.youjustgetme.com, beglobal, MiGente, who remembers me and small worlds.

If that was all there was to pingfm I would be thoroughly thrilled. But here is the second killer feature. You can send your post to pingfm from Hootsuite.

Why is that a big deal you ask? Hootsuite will list all of your twitter profiles and allow you to easily make a tweet simultaneously from one or all of profiles. You can also schedule those tweets for anytime. Plus, you get other screens that show retweets made from any of your profiles tweet – allowing you to retweets or direct message those other people from one or all of profiles.

Hootsuite also contains much more like an auto RSS feed from your blog  (or dare we say it, all of your blogs or anyones blog or RSS feed)!

Using Hootsuite

Using Ping.fm

Once again, they are both 100% free. Mega way COOL!

Twuffer is an easy to use “Twitter Tweet Scheduler” for Free.

This video shows you how to do this easily. It works great but things like social oomph (formerly called tweetlater) do the same thing and more (also free).

Tweet ya later!

Oom Pah Pah it is not!

Tweet Later was an easy name to remember. But alas, it is now Social Ooomph! Egads, that name is even worse than twitter! But, the service is good and so is the price – FREE.

Yah yah, the basic service is free – but it works for me, for my needs. Here is what you can do for free.

Send An Automatic Welcome To New Followers - This can be the most crucial part of your follower contact. They are online and interested in twitter now, not the next day when you happen to login and notice you have a new follower. Besides, how do you currently track who is new!

Schedule tweets – If you have a rush of adrenaline and have lots of tweets you want to do, you can space them a part. This makes you look like you are awake and functioning when you are actually passed out on the couch or just enjoying the daylight.

Autofollow – You will automatically follow anyone who follwes you. Not only is it a common coutesy to follow anyone who follows you, you are likely to be dropped if you do not follow them.

View Mentions and Retweets – A quick recap of who has mentioned or retweeted you. Find out which people respond to your tweets and focus on them.

Track keywords on Twitter – This is essentially your own search engine. One that works for automatically. You’ll get an email showing you who has used whatever keyword you are interest in.

URL shortening and Tracking – Here is a great way to see how many people actually click on the links in your post. Do you currently know that now?

Save and reuse drafts – This works great for common text and url’s you use. Of course you can also list them in a sparate notepad file too (do whatever works best for you).

Vet new followers – Here is a common cause/term of confusion. This process lets you interupt Autofollow & Autounfollow so you can weed out unwanted and irrelevant people.

Cleanup your Inbox – This automatically removes direct messages older than 7 or 30 days. A nice little time saver.

Personal tweet engine – You can schedule added tweets that do not go into your twitter profile.

Mutiple Twitter Profiles – Now you can manage mutiple twitter profile from one Social Oomph account for free.

Now some of you people are in a real twitter twap and need more tools than the casual twitter does. Not so surprisingly, the social oomphers have more tools and twicks  for you – for a small additional monetary sum (money) you can get the professional version.
