How often do you change your Avatar?

For Steam, I change it once every two months about. Mind you, it's not a set thing I do on a routine, that's just about the time it takes for me to desire a change. On StarCraft 2 I've used the same avatar since I unlocked it (<3 Mira Han). I think I'm still avatarless on my PS3 and I've had it for quite a few years now. On AIM I was avatarless for years, until recently I think I've changed it two or three times. Most other places, if I set an avatar, I leave it be until the end of times.

Google me and see.

Haven't yet, but thinking about doing it soon.

I'm more bothered by nick changes on steam, gladly it keeps track of the changes so you can always check the older ones if you forget someone. There's some people on my list I have NO IDEA who they are, though, and some I only recognize because their accounts are tied to facebook, haha.

On msn neither of those really bother me since I just remember people by their emails anyway. On MSN I used to change my avatar according to my mood (so many times a day some times) and my nick changed pretty often in the past as well.

On steam I don't really plan on changing my nick unless it's a special occasion. My avatar.. doesn't really change thaaat much, since it's a picture of me and I don't take pictures very often. :P Then again, sometimes I get tired of having to see my own face, so I have to change it a bit every now and then so not to go crazy.

Second avatar I've had since I registered on Steam in late 2010, I rarely change. Once every year or so

never

I hardly ever do it. Only reason why I changed to my current one is so im kinda unique.

haven't changed for years

This is only my second one since registering on Steam, so not often.

every now and then

Never changed mine in 4 years

Saw somebody in SG with my avatar, changed it.

I had that avatar for 2 years :U

Year by year.
