Greetings!
Basically, tribes are like tags that come with a side token.
So when creating a post you tag the appropriate things and this will cause you to earn the normal rewards (HIVE/HP/HBD), but also whatever secondary token like LEO or SPT.
This also organizes them so front ends can show SPECIFIC topics.
LEO for finance and SPT for Splinterlands.
There are tons of other front ends on hive.
Write wherever you want and just tag appropriately.
But yes, generally, don't tag something that has nothing to do with it... this angers folks. 😉
And no, I don't think there's any easy thing to point you towards... The beauty of decentralization: ain't nobody in charge, thus, ain't no central location to find information. It's a big ol' sea of fishes out here.
Good luck! Hope this helped a little.

Wow thanks a lot. Yes, this was more or less the idea I have got during this days, but you have structured it better. SO basically, any interaction I do, lets be in d.buzz, Hive blog, Leo Finance, a game, etc... If I tag to one tribe it will appear there... WOW.
