We talk about it — but I don’t actually offer any suggestions. I share with them my own experiences — and experiences some of my friends have had. When I was first on twitter, I used a pseudonym and a photo of a water lily, which matched the pseudonymous blog I’d kept for years. It wasn’t until two years ago that I decided to add my full name (although I kept the writingasjoe part). We talk about the pros and cons — with all of us chiming in about stuff that has happened to other people we know — and that helps them up their own minds. My only rule is that I have to know it’s them — usually that means that they toss their first name in there somewhere.
