I'm pretty sure we all get that rendering bug. It's just how the page is designed. Also problematic, is that the tags are the same color as the summary, clicking on them no longer does anything, and sometimes multiple instances of the same tag will appear. Plus they are mostly useless for searching, unless you happened to want to search for all "kdawsoncrap", or "crybaby".
I didn't mind tags at all when they were in beta. They were a different color, therefore standing out from the summary, and you could click on one to find more articles with the same tag, although you could only find articles a month or more old. I don't recall ever seeing duplicate tags. I would not have considered turning them off, because while they served little purpose, they were funny and did not cause problems. I find it disgusting how Slashdot simultaneously decided to fuck up tags, remove them from Beta, and made it more difficult to turn them off. Sometimes I think Slashdot is trying to fuck things up just to get people to comment on how fucked up things are, therefore increasing comment count and page views. It works, but still.
I am quitting Slashdot. Are there groups for that sort of thing?
