I find the character limit a interesting limitation, both negative and positive. On one hand, as you say, it's impossible to have a nuanced discussion in 280 chars. But on the other hand it forces (and allows) people to write interesting things in a very concise format. Should be noted though that I only interact with twitter trough Tweetbot and with a extremely curated follow list. And in this specific way I find it's a great way to keep up to date on industry specific news and learn about new things (by following people in other industries). It's far from perfect but I have not found any other way to keep up to date with the thoughts of people I look up to or find interesting. I had high hopes for micro-blogging but it has not caught on yet.
