I had a few minutes to spare this morning and decided it would be worth it to see what a Fat Tweet might look like, one that has room for more than 140 chars, that doesn't force you to click a link to see the rest.
I think you can figure out how it works.
If you think this destroys the utility of Twitter, I'd like to know how.
PS: The reason this is needed is simple: People don't click links in Twitter.
