Exode is missing: its a game on hive.
Hashkings is another game on hive though it's super alpha atm.
There are also the weedcash communities sites, hive list and the hustler community, they aren't super huge but they are still actively developed by @thelogicaldude
I feel like adding exchanges is not really worth it. Better to have more space for more meaningful info, people should easily be able to find out about exchanges by other means.
Other than that I think it works pretty well.
Communities I run: Gridcoin (GRC)(PeakD) / Gridcoin (GRC) (hive.blog)| Fish Keepers (PeakD) / Fish Keepers (hive.blog)
