The thing is, browsing through community list, discovering communities you had no idea exist can give you idea about what to post and help you going forward.
Thanks for letting us know about "Sloth.Buzz". I'm sure there will be people interested in that too. If there's a community set up already, then it is already included. My list is just a part of the communities as it's impossible to include them all. Also, no one should limit themselves to this list, we have an amazing search function, provided by PeakD, which helps you brows through all the communities created on Hive.
Yes, I only recently discovered the full "communities" tab and potential the other day, don't ask, it's a sloth issue! There's an awesome amount of niche communities out there waiting for people to get involved!
I just posted to the 500 words a day community, referencing this post and challenging others to make a post into a niche community tomorrow! (or today! Why not)!
Thanks again for the list, i'll be saving that for future reference, hopefully my tags will start reflecting my content more increasing the chance of it being noticed!
That's a very good idea!
