Now that I work with the "Father" of wikis, I decided that I really ought to get into working with one. So I am the proud owner of the SOA wiki on the internal Microsoft wiki site. I must admit that so far the progress is a little slow in figuring out how to get things done. I keep wanting to do the low level HTML things that I am used to and I can't quite figure out how to do them with wiki.
Of course, wiki is a trade off between the complexity of HTML and the simplicity of collaboration that wikis are famous for. If I could just figure out how to do bookmarks and intra-page links, I would be much happier though.
