I really enjoy the community and the moderation system on Slashdot. The combination of the 2 are working well together, in my opinion, and I told them that.
I also lambasted the editors for not editing, for headlines that are downright false, and various other editorial issues. One thing that stops me from suggesting slashdot to my friends is that I never know when some story is going to get posted with completely false information in the headline or summary, with a 100+ comment conversation that ensues about information that isn't even accurate.
When that happens, and it happens often, it makes the site look foolish and by extension it makes me look foolish for having suggested it. Slashdot needs to tighten up the editorial department, for me that is the single biggest area for improvement on the site. I told them as much.
