Googling your name shows a lot of relevant online presence: do you look less professional?
raganwald: What do I think?1. I think you look a lot less like a forty-something or fifty-something business manager, but only because most people of that generation who weren't in computers grew up with Usenet, mailing lists, or BBS's. So if their idea of "professional" is to be just like that, no, you don't look professional.2. I think my children will laugh at this question: They will grow up being on CCR 24/7 in public, with facebook and its descendants being their social hubs, and with everyone able to see transcripts of everything. That doesn't mean your question is laughable, only that this is a very temporary phenomenon driven by a generation gap.
