I think so. My blog is a mix of everything (personal, technical, random). It is a really good way to learn to be a better communicator. Especially when you have trouble keeping thoughts in order.

It also takes time to get better at writing in general so (IMO) the sooner you start the better.

I never consider myself an expert (in anything), even though I think I am competent and get paid to work so clearly my skills are of use.
