Mmm... not often... I only check two things obsessively... AIM mail and Facebook xD
But I do check subeta obsessively ._. it's sad.
I have them all on my Firefox Bookmarks Toolbar thing, and I check them, like, every half hour. xD
Them meaning (in this order)...
-Subeta -dA -Twitter -Facebook -AIM -dA again because I always forget -Back to Subeta
The only two sites I immediately check are Subeta and Neopets... but I always sign into my three messengers (AIM, MSN, and Yahoo) to talk to people or see if I have any offline messages.

Oh, this x100. I alternate between checking FB and Subeta obsessively.
I do that, even though I know I don't. ._. I check my phone every 5 minutes, didn't hear it ring BUT MAYBE THERE'S A TEXT.
Remember April 20th, 2011 when we thought the world might end, when the PSN was down? These guys do. Reminisce those horrible days, the catastrophic events! The homeless men! ...And, is that water orange?
Depends on what accounts.
I sign in to them when i can think of them, but not for any particular reason. Not the "omg what if someone wrote on my FB wall" reasons.
I used to have like 5 email accounts because I'd get bored of one or have too many people I didn't want to talk to on my lists so I'd create another xD I used to know the pw for all of them but over the years I've forgotten all pws except for 2. :(

I do that. I'm on Twitter or Subeta all the time... Sometimes I even sign into forums I hate or don't go on anymore, just to make sure I don't have messages. x.x
I pretty much stay logged into subeta all day, even when I'm actually working. I check it pretty frequently while I'm working; I tend to not log in at all most evenings after dinner. I go on Pogo fairly often, although I don't chat there, I just play games.
I always sign into me Subeta, facebook, and Dragon Cave accounts. I'll sometimes sign into me forums with me dragon's bios (Nessus, a geek point to all those that know where I got that name from), which I now have open all the time since I'm writing a mini-series about one of me dragons. I'll sometimes sign into DeviantArt. Though I don't sign in there a lot now.
i've actually tried to delete the accounts i don't use. :x i just check my hotmail because it normally notifies me through mail if i have a new msg or something. and i log onto twitter religiously =)
(This is creepy. D: Did you just make this thread on Gaia, too? XD)
But yes, I do. Mainly, it's just to click around. Not because I have to check messages, but simply because. :c
I have issuesssssss. And can't get off the internetttttt.
AM NOT. xD I just had a huge case of deja vu when I saw this. XD
I CAN'T HELP IT. D:
I check my school email obsessivley. like please let class be cancelled pleeeease
All the time. Right now, I'm logged into:
And I keep checking the tabs to check messages.
XD
-fails-
I check Yahoo!, Subeta and Facebook every day. dA occasionally.xD
I'm not the only one! :o
I do that too. I've bookmarked about 8 of the sites I visit daily, and I log into each of them in that certain order they're in. Darn OCD. ):
I always check subeta, da, bebo first thing when I get in from school.
Then I go about my business but if i ever post anything on da i check my messages obsessivly for comments and the like - about every 2 minutes. not that i get many, haha.
