I've just started a new site just for IT issues. It is hosted on Google Sites because I want to play with that infrastructure for a bit. The sites are easy to maintain through a web browser and serve as something between a blog and a full-blown web site. The site-wide search works perfectly and that fits the bill better than simply posting technical articles to a blog. Not that there is much practical difference but at least I can have a proper table of contents and differentiate between articles that go there and news and opinions that go to (this) blog.
