Many times i used to feel 140 characters in twitter is bit of constraint when tweeting stuff which are great than 140 characters.<p>140 perfectly suited for status updates.
but i feel twitter is much more than status updates !!!<p>What do you people feel?
I personally feel that Twitter is unsufficient when you actually have something to say, for me it's no more than status updates, some news or nifty one-liners. I hate to write, or read, when you don't have anything to say and Twitter's signal to noise ratio is too great for me to use it. Instead I read and write blogs.
I think the length is indeed a limitation for the person tweeting, but it gives benefit to the people receiving: short and sweet. It forces you to cut down to the point.<p>A twitter stream therefore feels like light reading. Low commitment. I suspect if twitter ever increased the length, their usage would go down.
