I've turned down invites to FB because I know HR now cruises those sites to sniff up things about employees and applicants. Aside from being good with computers, some of my other interests would probably land me on some watch list, if I'm not there already. I'm assuming that The One probably has a couple of billion-dollar departments doing data mining right now. Why? Because he can.
I also turned down a couple of invites from LinkedIn. That seems to be a high-end FB, where power brokers go to polish their resumes. It's for people who believe they're still entitled to upward mobility.
I also found out from a friend on LinkedIn that the trolls there are the worst she's ever seen since the days of AOL and Compuserve being the only online games in town.
I’m not enough of a power broker to even know what linkedIn is. :~)
I’ve settled down a little about FB. I understand how it works a little better.
It’s a little overwhelming in it’s ‘flair’, but it’s not as ‘open’ as I feared.
