Just ran across the tableless tag and not really sure what to do about it. My first instinct is to burn it. It sounds a lot like tagging something with "not using tables" (similar to tagging with "not javascript"), which is a purely Meta use.
Designing pages without using tables isn't really something new. It's always been the way you're supposed to construct your HTML, people just didn't seem to care. With only 53 uses, it doesn't appear to be in any form of popular use. Should this tag just be destroyed, or does someone else see something in it that's invisible to me?
Note: I've already killed off the table-less-design tag, which made absolutely no sense with that hyphen in between "table" and "less" (and also only had 9 questions).
