The change will be nice because it'll hopefully be easy to parse the metadata for attachments (images, url) and it should be more elegant to handle them in general than regexping them out.
Knowing strategies to avoid just nasty people is the main issue I have with it. Like, if you go into Twitter and see that you have a whole bunch of Gamer Gayers targeting you (just an example, I can't see how I would be a target!) then I'd imagine having no Twitter would be preferable to actually having a Twitter account!
Perhaps refrain from using childish insults like Gamer Gayers. Like attracts like.
Either way, yes, out of all the words to misspell, that one was quite unfortunate.
To some people it's so valuable to use as a means of participating in their community of choice that they're willing to keep using it despite severe harrasment.
Not being a woman gives you a big advantage against harrasment. But it can come from all sorts of weird places. My wife is a big Eurovision tweeter and encountered people who search for "Macedonia" to tweet Greek nationalist abuse at.
I follow several programmers (some internet famous, some merely who I've found from using a project they worked on or someone else's retweet), and through that, find it interesting to get a glimpse at what other people are doing or finding challenging, or see when there's buzz around some new technology in my space.
The other thing I find it useful for is local updates in my (relatively small) city. Traffic updates, road closures, police activity, events, etc. The local public works and city hall accounts are surprisingly active and often useful. I also follow a handful of restaurants nearby the office: they often tweet lunch specials.
I follow exactly zero mainstream celebrities, never look at 'Moments', 'trending', etc -- I find those things full of crap I simply don't care about at all.
