I do not use Twitter as much as I used to. I follow 163 twitter accounts, and I probably pay attention to less than 10 of those. The ones I really care about are my friends and family, but sometimes I will take a look at the others in my feed, so I keep them. Here are a few I enjoy:

@DailyShowtune - This is one of my favorites. They post lyrics a few times a week from Broadway shows, and invite all their followers to guess what show they are from. It is fun. I do not know them every time, but I do most!

@FakeAPStylebook - As a former newspaper copy editor, the AP Stylebook was my bible. I still refer to it and keep to it when I can. I kept my resume in line with AP style. These are more spoofs on that, but they can be quite funny sometimes.

Most of the random twitter feeds I follow are Broadway shows, Broadway actors, librarians and YA authors. Here are a couple randomly selected samples:
