Heard about Twitter but still don’t have a clue what it is and what’s its value for your business? Well the Twitter team has answered both your questions with their new Twitter101 guide. The guide covers the basics of Twitter from its lingo to its value as an effective communication medium to strengthen relationships with your customers and consumers.

Twitter is popular for its 140 character post format, which we now refer to as Micro blogging. This is the single most appealing thing for me on Twitter – to share my thoughts in just 140 characters and in essence, save a lot of time. Apparently, some people have difficulties doing that, and require a few more characters at their disposal. This is where services like TwitterContd come into play.

The TwitTrend is spreading like wildfire these days. Every other person you bump into would be tweeting that he has actually stepped out of his home today, or if he’s any geekier, he would tweet with a GeoTag to his exact coordinates.

And thanks to an open API, developers have found a fun way to kill their spare time with developing innovative web apps around Twitter, some of which hardly add any value to your experience. Without further to do, here is a list of some of the apps I find good, but would probably never use.

Just when you thought that no one else would be stupid enough to make another twitter app that lets you post your RSS feed to your time line, along comes TweetMyFeed. TweetMyFeed is yet another humble attempt at something which other services, TwitterFeed for instance are doing perfectly.

You’d run into a lot of Lifestreaming services these days. You know the ones that take your Tweets and your Flickr photo stream and mix them up with your Facebook news feed and Last.FM scrobbles. A lot of services let you do that now, and they come in all shapes and sizes, like FriendFeed fr example. Even though there are a lot of services that can mash up your social activities, and publish them to the web, we still haven’t run into a lot services that make good use of those streams.

Skimmer is one example. This beautifully designed Adobe AIR application by Fallon gathers your social streams from different services all in one place; for pleasurable viewing.
