Apprec the video. I myself didn't find it difficult at all in the yrs here to find people with similar interests when looking through basic #tags, so communities doesn't solve that for me but has done the opposite for now in adding quite a bit of confusion on how to operate going forward lol.
when you say it only posts to those communities, does that mean that nobody outside of the community can see it? If I post in the Steemleo community and use the old '#steemleo' does that mean others cannot see that post on steemit.com if they aren't joined in the community ? or would using the hive tag and the old tag show to both crowds?
can you only post in 1 community at a time? I see you posted in a 'hive' here and used several older tags, I assume because those tags dont' say "hive' that they don't go into those communities if there are any of that name?
