I was at first just going to mention this to Jason, but I figured that maybe some other people may be interested as well. Anyhow, I’ve recently discovered an excellent CSS mailing list — CSS-discuss. It’s administered in part by Eric Meyer, which gives a hint as to the caliber of the list.
I’ve only been subscribed for the past week or so, but I’ve found the list to be very helpful. And, even if I’m not asking the questions, I find that answering CSS questions of others allows also me to keep my skills sharp.
I’ve actually been subscribed for months (to the digests). While I’ve found some good information occasionally, I find that there’s a lot of question-repeating, and the list is too high-volume to read through consistently. There are also a ton of requests for “site checks”, which are hardly of any help to anyone but the author of that particular site.
It’s a great resource for finding answers, though, by searching the archives.
