Not just because I got a brief mention, but because it is great site, I want to put in a strong recommendation for the site Women Learning Thai. There are a lot less Thai learning resources on the Web than Mandarin resources (although enough to be highly useful), however Women Learning Thai is about as good as they come in either language. A lot of posts covering reviews, other resources, instructional material, culture, guest writers etc. etc. etc.
What is most pleasing is that the site is pretty much approach neutral, although Catherine Wentworth is happy to present her own views on approach to language learning in posts or comments, other views and approaches are equally well represented, the interviews with successful Thai language learners for example. I think this is a key factor to the success of the site as a learning resource.
BTW although I was a little nervous at first, men are welcome :). I can only recommend that new Thai learners start by browsing there, if not I sure that gravitational force will pull them in soon from other parts of the web.
I notice my RSS feed from the site on the left-hand side is obviously the wrong one (I'll fix that).
