Eriz Zorn has some quick interesting takes on social networking. For starters…
1. No, I will not join your network on Linked-In. I’ve drawn the line at Linked-In. I’m sure it’s a fine service and very valuable to some, but I’m already over maxed out on these kinds of sites. […]
2. Here’s a guess as to how Facebook is going to make money: Once the service reaches a critical mass of users — and it looks to me as if it’s close — it will offer one or more premium levels of membership. […]
3. I hate Facebook’s “wall.” Actually, what I hate is how I can’t easily respond to what someone writes on wall on my own wall. Instead I’m supposed to click over to the other person’s wall so we can conduct a “conversation” that’s almost impossible for anyone to follow. […]
Should you post about your routine, daily activities [on Twitter]? I tend not to, but we’ve been involved in a Tribune company round-robin e-mail discussion today about a letter from a reader who argued that too many Tribune Tweeters weren’t coming off like “real” people.

if he doesn’t know how to do wall-to-wall, then he is not stalking properly. it is very easy to see what you have said to one another and to respond.
Good point. It’s like an amateur complaining about something that he knows nothing about.
