Twitter is one of the best microblogging tools, and a status update site has been quite popular lately, and one might not believe it when you say that its going to reach 1 Billion updates or Tweets by the members there.
My profile has got just 2200+ odd updates, and many friends of mine have somewhere in thousands. Total count has been rising every second and in around 13 days, the 1 Billionth tweet would be coming.
Check this popacular gigatweet website to see the countdown to the billionth tweet.
As of now, there are around 13 days and 20 hours left for the mark to come, and the number is just increasing and at the moment of writing, 980,405,921 tweets have been completed in twitter.
This might be an assumption, but the one who created it might have taken the frequency of tweets per minute into consideration and have created this.
Follow me at twitter if you are already there, and if you are still not a member there, register and follow 
You would enjoy the place.
1 billion tweets, that’s a big number!
I will the proud one to make the 1 billionth update….
I am sure I am among the 1 million
I tweet too. 
1 billion.. Yippie
Thats a great news for them.. They will get the perfect new year Gift already
10 more days to go for the 1 billionth tweet, i think twitter will reach the number before the date as the number of users are increasing constantly and the number of tweets as well.
