On Monday, I reviewed Yahoo! Personals, and not particularly favorably. The most interesting thing about having a Yahoo! profile, and the reason I haven't deleted mine, is that even if you don't pay for the service, if you're signed into the Yahoo IM system, people who like your profile can IM you. It sets up a separate IM profile based on your personal profile, so it's not obvious to the people who see your profile who you "really" are.
Naturally, however, this leads to a whole additional set of advice for men striking up IM conversations with women they don't know. Here are a few tips:
1) If you're starting a conversation with me, it's because you've seen my profile, which includes pictures and information about me. Please, for the love of all that's entertaining on the internet, don't pull the, "Hey, baby, what's up?" and expect me to be instantly fascinated by you.
2) It's especially useful if you start the conversation by saying that you saw my profile, what caught your eye about it, and either giving me some information about you or giving me a link to follow to read your profile.
3) I swear I'm going to maim the next guy who starts a conversation with me with a "buzz". This is a function that causes my IM client to make a loud doorbell noise, and it does, in fact, get my attention. But it's extremely intrusive and annoying. There's no need for this -- most people have their IM clients set up so they get notified of messages, and if they don't, it's probably because they don't want to be disturbed.
4) An IM conversation is not an entitlement to my time. I step away from the computer on a regular basis, or I may be working and need to focus on a task. Sending repeated "Are you there?" messages does not impress me. I'll get to you when I have a moment, and if I don't, I've probably left the computer for a while. If you need to leave, you can say something like, "Sorry you had to step away! I hope we can chat another time."
