Thanks for the summary and links after last night's meeting. I like your analogy about traveling to a different place and the value of being exposed to a different language and culture. Sometimes WordPress does indeed feel like a foreign land! But if you keep going there you always learn something new! And I always meet interesting people at these events.
I would be happy to discuss .com themes at a future meeting. I haven't checked the date for any potential conflicts but will do so. The linked site in my signature line below is only one of many WordPress themes I am actively using. I can discuss why I chose this particular theme and the others I am using, as well as the factors that go into my decisions about where to host my sites (I have some .org applications as well).
