He mentions Trump by username in some tweets at least, so that could be considered "harassing" (depending on scale though).
The one time I found twitter to be far superior is when I heard gunshots outside my apartment and found the location and a pretty good understanding of what happened within a few minutes.
A couple years back there were, literally, a dozen police cars on my street and traffic blocked in all directions. I discovered on Twitter searching Tweets near to me that a man had barricaded himself in an apartment around the corner. He had a hostage and when he started lighting the apartment on fire, the SF SWAT team killed him. [0]

I don't have an account but it is very useful if I want to see is a program updated to a new version, how a politician feels about a recent event (or wants us to think they feel), or live updates to current events. All that may be possible with Facebook, but since I don't want to always be logged on, I have a huge pop up and annoying captcha
I was vaguely interested in it (Twitter) when the Iranian purple revolution was going on, but that passed, and after that version of tweetdeck did as well, I've never been able to track topics well enough to make it more worth-while (to me) than a meme-tracker.
Other than that, I haven't found much use of it. I'm guessing that puts me in the dissenting position, but this isn't the first time that's happened.
>Tweets: 2,400 per day. The daily update limit is further broken down into smaller limits for semi-hourly intervals. Retweets are counted as Tweets.
Anecdotally, I've found several useful tidbits on twitter that are less than newsworthy (maybe because they are not interesting to a large subset of people) but that never popped up other places- I'm probably not using it correctly though.
More and more, I wonder why Twitter is so popular. I never really "got it". If I want news, I can go to a news website/aggregator. If I want memes, I can go to Reddit/Tumblr. If I want to talk to friends, I can use Facebook. Twitter always just gives me a headache.
