Occasionally, people I don't know will post comments on my blog (like you, DS). But I never comment on comments. And here's why: I can't.
Here in Beijing, I can't even read my own blog, or any others hosted by blogspot, without going through a proxy server. I can see the comments that people leave me, but I can't respond. And I can't post comments on other blogs, the ones I access via proxies.
So, please know I do read comments. But unless I know your email address, you won't hear back from me. Keep the comments coming, please - it's fun to see who is reading. Well, except for when it's creepy.
Ahhh, China. Gotta love those censors...
