I don't think that this should be currently one of our primary concerns. I actually think that we will develop better when people have to do a little research to find us. Besides, with the number of answered questions growing fast, and those answers being indexed by search engines, very soon it will be quite straightforward to find us for anyone interested.
On the other hand, WRI takes some responsibility for anything the company puts on their official recommendation list. Since WRI has no control over this community (which I think is a good thing, in many respects), mentioning us there may be a responsibility they don't want to take.
Finally, we are still quite young as a community, and it takes time for other interested parties (WRI etc) to become convinced that we are here to stay.
All in all, I would not worry about this much and just keep going. Things like that should IMO always be side effects of our true usefulness and popularity, not the other way around.
