The case for blogging, beyond the hype:
If you have something to say, then a blog offers a cheap, easy global medium in which to express yourself. This is as true now as it was three years ago, regardless of what the groovy cats in Silicon Valley may be up to.
Whether you have the time and the talent for it, “i.e. the skill and the will”, is another matter altogether. Also, whether other people will want to read it, is something one has little control over. But in both cases, the same is true for all other media.
That’s a big if.
