The problem is that, to speak in over-broad stereotypes, everyone under 25 grew up with blogs and agrees with you. Meanwhile, everyone over 40 thinks that you are a dangerous loose cannon who might blab the Vital Corporate Secrets all over the internet and embarrass your boss. This kind of creates a dilemma for those of us in our mid-thirties, who can see the future but who sometimes have to move in a world that's run by people who don't.

I think the ultimate answer is... it depends. I will say that, if you don't like to write blog posts, you probably should avoid starting a big, echoingly empty blog and just use something like Twitter, or a microblogging engine, or Facebook to establish your online presence. This is kind of why Facebook is there -- to allow folks to express themselves online without having to write entire paragraphs full of interesting and original prose. Not everyone is cut out to be a magazine writer.

The ultimate coward's answer is Linkedin, a site which basically caters to frightened 37-year-olds like me who know they need an online presence but are afraid to actually say anything.

I think having a blog is good for my own career, but unfortunately my blog is really lapsed right now because I find it much more entertaining to reply to posts on news.yc. :)
