@the prince,
PrinceG, I'll just add, and then I hope become quiet, that general isn't used much as a tag anymore. Too.... general.
The whole phenomenon of tagging is interesting, and we, of course, have threads about the process. We changed to tags in something like, ah, august 2008. A lot squawked mightily but we've gotten used to it. I find it really useful - but there are threads before 8/08 that only had the tags of the older a2k forums (like general, pets and gardens, etc.) and those are still how you'd find them. Some of us maniacs went back and tagged some threads/subjects that interested us more specifically, so you do see some older ones with the newer more specific type tags in addition to the old a2k forum descriptions. Well, I tagged all of the pets and gardens threads (gaahhhh!) and others did similarly.
There are two ways to search. In the New Posts page, look to the right and see the search box - stick in a tag, perhaps only a guess. Then you'll see threads with those tags.
Or, go to the top of the page and click on 'search' in the dark blue banner. Often I find things there that I don't find in the tag system, sometimes easily.
There are also arguments by some about the use of (what is the word? call out?) kind of tags, pro and con. Robert has said he means to change the system with weighting, but is busy in the meantime.
