blogging or questions sites?

I've found that Yahoo Answers is an interesting site (sorry Google!) I regularly go to the health section and have put in a fair few responses under a pseudonym (it would really give the game away if I called myself BillyBobCartwright). I get amaized at a number of things. Question and answer sites seem to attract a fair few idiots who think that if they got on the internet they will always get good advice, when if you look at some of the advice it is really dangerous or unhelpful. Some situations sound medical emergencies and you would think anyone with one ounce of sense would go straight to their nearest ER. It is especially interesting looking at those questions about conditions with which physical therapists work as it gives a flavour of the common misconceptions about health. There are more question sites than Yahoo but theirs seems to have more interaction, but let's hope that Microsoft does not buy the company because that would mean a further extenion of the Gates monopoly. Some of the questions might be better put on a blog.
