We keep saying "when communities will be here" we'll do this and that.
Wrong! Communities are already here! You can see them all around if you look.
There is a very large photographers community, and they have some specialized curation projects.
There is a musicians community. Are they using @dsound to share their music? Or maybe @dtube?
There are artists and poets which also found a place on Steem, and some found big curators for their posts, sort of patrons of arts. @steemitbloggers, @freewritehouse support writers, right? @SteemPress is an option too for those who post on their own Wordpress blog.
We have the scientists community and @steemstem is the place where they get together and share their insightful posts.
Developers usually post on @utopian-io or hang out on SteemDevs discord server (that's when they're not coding) or on GitHub, working together to grow projects up and fixing bugs.
Witnesses have their own channels of communication on SteemChat (but anyone can watch if you're curious).
Gamers hang out on the veteran already Steem Monsters or the fresh hit, Drug Wars, and on their discord servers.
Physically active people love @actifit! They have the mobile app, the desktop app, discord and now a weekly broadcast where they can be as a community.
You like to stay in the loop with the latest tech news? Then you probably like @steemhunt, which rewards you for sharing your hunts with the community.
Are you a @partiko fan? Do you get notified whenever someone comments or replies to you, and since it's on mobile, engage right back? There you go, another big community!
And then there's PAL, the biggest discord community related to Steem, with an impressive 20k members, from what I've heard.
And many other discord communities, some smaller, some bigger, but all about Steem.
And then there's the use case. Are you a (manual) curator? There are many communities revolving around curation.
Are you a content creator? Many are. Which dapp do you usually use? There you go, another community, based on the dapp used. Sometimes there are stronger ties between certain dapp users (see dtube, actifit, steemhunt, etc.), other times it can be a matter of seeing the content of fellow dapp users more often.
There is a distinction between what communities are now and what they will be when they will be coded as an embedded thing on Steem. In a way, but much more flexible, it would be like adding tournaments to Steem Monsters. You can still play tournaments on Steem Monsters now, but not only from inside the game, you need to use two other third party apps for that.
Communities are here! Don't wait for them and don't use it as an excuse to delay building them.
