Why Twitter would be right to expand to 10,000 characters – in 10,000 characters

Would a new character limit be good news for open debate on Twitter - or would the end of brevity just be an excuse for more ads?

What if Twitter ends up letting you make 10,000-character tweets? Well, why not?

At last, we'll have plenty of room to couch our situational comments in actual context. We've all been there before: two years ago, you livetweeted a movie. And yet, today, you get a baffled reply to one of the two-year-old livetweets from a stranger, who didn't get your joke, or who didn't understand what you meant. They might not even realize that you were watching a movie! Who are these people? Your tweet had a context, once. Wouldn't it be wonderful if you had enough space, enough characters, for it to have a context forever?
