What are you doing to promote the hobby? It's just too bad that the question has to come up as a criticism of harsh words related to the 5e covers that have been splashed about the Internet this week.
What am I doing to promote the hobby?
I am playing, and promoting, Dungeon Crawl Classics RPG, including running World Tour events. The new D&D covers do not "do it" for me, although I think the Starter Set cover is the best of the grouping, and the DMG cover is not too bad.
In my neck of the woods, rpgs are not dying at all. I personally find the multiple covers of the DCC RPG to be evocative, although I like the red "fire" cover the best. The interior art not only has energy, but strongly implies story.
(And I do not mean "character building" or "railroad" by "story"; I mean a sequence of events that might happen in the game, or in a good pulp fantasy story.)
There are a lot of RPG materials that inspire me, and that I enjoy. I do not feel a need to pander to WotC's current iteration in order to "do something" for the hobby. I do not feel that WotC need even do well for the hobby to prosper - Paizo has taken the lead role these days, and there are games waiting in the wings to steal the top position should it become available.
I am really happy with a game that focuses on adventures, instead of endless new editions to end all editions. That doesn't mean that I would never play 5e, but I don't see any reason to switch at this point. I have found my bliss, and I don't need to spend $170 plus tax to see if WotC has something to add to it.
