Last FM

Occasionally use, but very rarely sign in:
Myspace (yes, for music)

myspace - still use it to hear things when they're not on hypem or spotify, etc but whenever i log-in i only have spam (usually from bands i have no interest in)
bebo - never had
friendster - logged in for a laugh a few months back, don't use it tho
last.fm - doesn't take much investment of time to 'use' it, although i don't really browse their site or use it as a social network
facebook - rarely log-in apart from doing DiS updates and looking at pictures my mum's uploaded of my cat
twitter - too much
flickr - never used it
msn - don't use it anymore, i use iChat for AIM, Gchat and also Blackberry Messenger

Be curious what networks people are increasingly using at the moment. I'm still yet to find something that solves a lot of time under one umbrella and can neatly filter things out, although I quite like popego for this reason.

myspace: Never had an account, but use it to check out bands.

bebo: No, I'm not Irish, 14, a massive townie, or a combination thereof.

friendster: Nope.

last.fm: I scrobble to it, and use it to check out bands. Added some DiS peeps but don't know anyone from IRL who's on it.

facebook: Yeah most days, but locked down with no apps & no wall, & no IM. I just use it more like a secondary email inbox with the daft twitter-ness bolted on, really. I post the odd comment to reassure folk that I'm stalking them from afar.

twitter: Can't justify getting an account. But I use twitter.com/search and oneriot.com for real-time searching that google news hasn't picked up on yet.

flickr: I've got an account with nowt on it. Picasa has been much more useful for sharing albums with people I know but keeping it private from the wider world.

msn: Not for the best part of a decade. It's been deleted fom my startup progs and windows registry so that I never have to see it again.

Others I do use: delicious, skype (v v occasionally)
Others I don't use: faceparty, deviantart, digg, reddit, stumbleupon, friends reunited

occasionally go on last.fm and myspace but don't have my own account.
never used any of the rest.
