I miss the ability to down-vote ballot ideas. Seems now all we can do is like an idea.
When I have submitted an idea in the past, it's been useful to see how many up/down votes it gets. In general, ideas seem to get little attention from the community, so now if I have 2 likes for an idea, I don't know if it's because 2 people looked at it and liked it or if 10 people looked and 8 thought the idea was rubbish.
And on a related note, I'd support just about any proposals for ways to bring more activity to the ballot ideas community. The old-school SASWare ballot used to feel like an annual event (when the survery came out, and when results were released). I asssume the online ballot is not providing nearly as much information back to SAS, given the low participation that I see.
(I apologize if that all sounds negative; I feel positive about communities.sas.com : )
