I keep thinking that I want a way to list out all of the DW communities there are (which would include the functionality for comm owners to be able to opt out of their comm being on the list).

I'm actively hunting for communities relevant to my interests, but sometimes, I don't realize something is relevant to my interests until I see that it already exists... so I don't know ahead of time what interests to search for. Sometimes I'd just like to scroll through a big big big list of every DW comm, and turn up some gems I would've never found otherwise.
