ALso: The World Famous Crank Report But the world famous Crank report is more of a soapbox kind of thing, i'm not looking so much for feedback there like i am with a pure social network like LJ.
My MySpace and Facebook profiles are all private to protect me from the likes of you. Yes, you. Linking, therefore, would be a waste of my time and yours. I do add people if they ask nicely though.
I sit in front of my computer eleven to sixteen hours a day.
I use social networking sites mostly as business networking. Only my Facebook account and one of my three Livejournal accounts can be truly considered "social".
MySpace - I think I only check this every couple of months now, found it too difficult to keep track of what other people were doing. Since I'm not as big a music fan as most people, it doesn't have quite as much interest for me.
Livejournal - This is just a feed from my main blog, although I use the Friends page quite a bit for various blog and webcomic feeds.
Facebook - This one probably gets the most use, for seeing what various friends and acquaintances are up to. It seems to be the new Friends Reunited, I've been able to catch up with a few old schoolfriends that I lost contact with years ago.
I'm on Flickr and Twitter, but don't really use the social aspects of them (just store my own pics on Flickr, and use Twitter to update my blog remotely).
I've probably signed up for a few other random ones over the years as well.
these are the only useful ones until i wade into the mandatory myspace, facebook, virb, and so on once i finish building a real website to promote. some listed here are utterly new to me, and actually useful. thanks.
Mandatory Myspace, facebook, deviantart and a dead flicker begging to be restarted. Nothing canon happens on these pages for me, I only use them to watch my friends.
Had a MySpork years ago, then started a music one, deleted the first one because it was pointless having two accounts, then finally deleted the second one because... well I think it looked at me funny so I borked it altogether. I don't entirely recall what reasoning I had for doing that, if any.
MusoFinder - Sitting doing nothing, I think I've had 4 views in the month I've been on there.
MI7 - I've logged in a few times and found nothing useful, but have gotten a lot of email advertisements from them trying to sell me expensive recording software I don't need.
I'm looking to find a new one that is similar to MySchpamb, but not as stupid. I don't know if that exists.
