Really depends. If I don't have to be outside or it's at night when I am sleeping it can be nice and calming. If I have to be outside or at work (which is also normally outside) then no. Also depending on if the power goes out, then that's also a no.
Lame. Not that there's not cool stuff on there but i actually had to delete my account because an artist I liked and followed liked a tweet with an absolutely horrid message. The tweet made me so angry I just decided to give up on having a twitter account.
Cool. I collected a few back in the day. Unfortunately I tore all the tags off most of mine so they were worth almost nothing when I sold them years later.
