I can show you screenshots of tweets that are as bad or worse. The difference is that Twitter actually has built up, over time, the ability to moderate fairly well.
The value of Twitter isn't really that you can post and view small snippets of text. It's that they've developed technology that allows them to effectively moderate.
Any poorly moderated site eventually becomes associated with the right.
