Perhaps soon, but one thing that has always struck me about Basho (and maybe why Riak isn't as well-known as the other NoSQL DBs) is that they don't have a huge hype machine. They've always been more interested in fixing the problems with their DB and cultivating a community that understands the benefits/detriments of their database than blasting out "HEY EVERY1 SHOULD USE RIAK!!!" everywhere. Their site is very specific about what Riak is good at and what it's bad at.
I've seen many mailing list responses to questions about Riak saying "maybe Riak isn't the best fit for this, try looking at X..." whereas 10gen wants everybody to use MongoDB for everything.
It just seems to be a more honest operation, and people don't get burned as much.
As a paying customer of Basho who has had several direct experiences with sales and technical support, I second this. They are incredibly helpful in the event of a problem and are passionate about educating their customers to provide the highest chance of success with their products. They are honest about the limitations imposed by Riak and will go out of their way to help identify a solution. I have literally never had as positive an experience with a technical support team as with Basho. It is very refreshing.
MongoDB really is the MySQL of the NoSQL movement (http://dieswaytoofast.blogspot.com/2012/02/mongodb-mysql-of-...), which really, really causes issues. AFAICT, the mind-set tends to be
(1) Theres this new thing called NoSQL
(2) MongoDB is the biggest NoSQL store out there, lets use it
(3) Profit!
Omitting a - critical - step, viz., "what are we trying to solve for here?". The result, of course, is either people getting burned, or a bit of a mess to unwind, neither of which is particularly fun (though it is "Profit!" for others!)
Riak's relative obscurity actually serves well in this regard. Odds are that if you discover Riak, you do so for a reason - you've been searching, you have a specific itch that needs to be scratched, etc. Given that you are already pretty clued when you get to it, you are extremely unlikely to pick it for the wrong reason, and consequently the success rate tends to be astonishingly high.
Mind you, I'll add that the folks at Basho are some of the nicest people I know, and that helps a lot :-)
Bottom line - I really don't expect Riak to go away anytime soon...
