This will take care of the other commenters point about having to manually subscribe to everything. I just had it pull the top 500 communities from the top two instances and I’m fine…

The problem is you lose the ability to encounter new communities by browsing “All”. And since I’m the only user on my instance I will never discover any communities that I don’t manually add or find on third-party websites not to mention that process of using those websites is cumbersome and tedious…

I added the top few thousand communities and the server runs absolutely fine. :)
