A number of sites similar to twitter have come up in the recent times and people are using them more and more.

2006 was the year when twitter was launched and it has been revolutionized the whole concept of blogging into microblogging.People are now spending their most of time tweeting and making more and more friends.It has metamorphosed the way people use internet.Beginning from the individual bloggers to the worlds largest companies every user on an average tweets about 20-30 times a day.

It was twitters 140 characters text limit that gave rise to the need of Url shorteners.

Ok now lets talk about the real content of this article-site similar to twitter.

Sites that i personally consider are truely close to twitter in terms of microblogging are:

1-Plurk
2-Sweetter
3-Microblogger
4-Yammer
5-Tumbler

Now lets discuss in depth on some twitter like micorblogging sites/alternatives:-

1-Plurk.com
Launched in they year 2008.Plurk is a combination of a microblogging and social networking.I really love the interface that plurk provides

.Similar to twitters-tweets,tweets in plurk are called plurks.People can interact with each other and of course do online marketing as well as it also has feature of social networking.Plurk has a very cool feature of karma score-its like getting high hubscore in hubpages.And every time you update your profile,publish a nice plurk or anyine of your friends replies to your plurks-your karma score goes up.

2-Sweetter.net-sorry no documentation is present about sweetter in wikipedia.

Although it has a very unique name ofr a microblogging site but has almost identical page to twitters default page.
It too has the inbuilt concept of karma score.One cool thing about sweetter is that it has a TODO system-using which you can tell your friends what todo.
Like twiiter it also has a voting system where you can vote for the best sweets.

3-Microblogr.com

Though still in its alpha stage this little nifty microblogging site is really fast and similar to twitter it also has the feature to enable messages
via sms to your or your friends cell phone.

4-Yammer.com
Its been year since the launch of this twitter like micorblogging site and it has since then helped a lot of companies.
If you’re into blogging then please skip this part as yammer only allows people with same domain email to contact each other thus making it compact and full of privacy.Its like a personal microblogging of the companies and organizations and you can purchase a microlgging network from yammer as well,and the cost for that is not too high.

5-Tumblr.com
“24 reasons why you will love tumbling”-this is the current landing page of tumblr and believe me their are many more reasons why you’ll love tumbling.

Similar to twitter the text limit here is also 140 characters and they are called as tumbledogs. You can send-links,pictures,clips.music.Like most of the other microblogging sites you can fully customize your homepage in tumblr.But one unique thing is that you can even own your personal domain as well.

No matter what-twitter still rules as it has almost all the features of a perfect microblogging site.
