- Identify yourself, and who you work for, and talk about your companies issues
- Identify yourself, and who you work for, but don't talk about work things (i.e. leave it personal)
- Don't advertise who you work for (Not in your visible profile, or in your posts) and keep work/life separate on social networks
As a follow up question, if you're in the third of the above categories, how would you feel if someone managed to 'tag' you as being part of a particular organisation when you had been posting things without identifying your employer? That's a risk of twitter having introduced the concept of 'lists' where you can basically be tagged. Even if you 'protect' your updates so they're not publicly visible, people can still see what 'lists' people have added you to. So if you keep your personal and public 'social' activities separate, someone else can blur the line by tagging me along with others to identify me as something I didn't want. Is that a good thing?
I regularly get invites from people I know through work on certain
social networking sites where my profile is private. And most of them
get ignored. That's my choice. There are sites that I'll use to communicate with collegues
(Lotus Connections, LinkedIn), other sites I'll use to connect to
people socially which have private profiles (the likes of facebook,
myspace, bebo etc.) and there are sites that I use publicly where anyone
can follow me (for example twitter, where I don't protect my account,
but I also intentionally don't advertise my employer on there) and I moderate the
content of each appropriately to the audience, which I define with a
reasonable amount of clarity.
But there are plenty of others that don't seem to restrict their social
networking - am I in the minority in having a desire to retain work-life
separation? Or is this view out of touch with a generation brought up
on the internet - maybe work/life integration should now be considered
the norm, and in the future all friends are collegues and vice-versa, so
why make the distinction?
 - Lets take a more extreme example, what's to stop people tagging you by creating a list that suggests your a part of a terrorist organisation or other term which would be considered negative, whether true or false?
 - I could accept work collegues on facebook but keep them in entirely separate lists (but then that doesn't solve making all photos/wall posts visible to everyone)
