Always check the comments on foreign language blogs. You never know what folks are saying.
If your blog or site gets a lot of traffic from another country, be sure to use Google Translate to read the comments.
My German is respectable – I could make out that a couple of folks saw problems, and that they couldn’t get their sites to show up. I cut-and-paste the comments into Google Translate, found the bug they reported, and had it fixed right away.
Now I’ve got someone who’s German grammar is better than mine editing the response I wrote. I’ll post it on drweb.de as soon as they’re done.
