I have somewhat given up on REALTOR.com and whether they will ever have a definitive, market leading direction. It seems to me that this site is the worst-leveraged repository of information in the information age's internet real estate site boom. Of course, as an NAR member this is not very encouraging. It seems a classic case of the aircraft carrier unable to maneuver in a war of nimble destroyers and gunboats. Of course, I've so long ago written this off that it's possible something monumental has come out recently and I'm not aware. It's interesting that Fred Miller's recent post of the letter from Mike Long (CEO of Move.com, NAR's partner in charge of R.com) is dated a year and a half ago and quite frankly, for a lot of text, doesn't really say anything, so I guess it should be no surprise that it hasn't turned into anything in the time since its drafting?
The competition certainly seems to have managed to grab the eyeballs of the internet-savvy real estate curious public. However, that doesn't mean those guys have yet found a way to make money off that, and I'm not sure how many of them will survive long-term, even those that have gotten the best recognition (on this site that certainly means Zillow and Redfin), but that's what this post is about.
Is REALTOR.com all washed up? I don't think so. For all the lack of direction that R.com has taken, it still gets millions of people a month and it still has the most vast inventory of homes available and of market data, the later of which is (to my knowledge) still not being used by the site. 
There are invariably going to be multiple sites out there with strong niches carved out for themselves, and no one site can ever be all things to all people. Is there a way to be both big and small? I think there is. Here is just the most simple start of the answer: incubate and sell.
1. Incubate. With $100 million or something like that certainly Move.com/R.com can use a few million here and there to start a few smaller, niche sites, sites that operate separately, but with the support (financial and otherwise) and most importantly, access to the data of R.com. If you can't beat ‘em, join ‘em, or in my opinion, even better - OWN them (or at least a big percentage share of them). That's not to say that R.com should become an internet incubator as a primary business line, but given the huge name they put behind a project it will immediately give it additional credibility to get outside venture capital, the single biggest hurdle these companies face before they find a way to actually make money off eyeballs.
2. Sell. Why are we as REALTORS all paying to have R.com service when it should be paying us for what we give it - all its inventory (homes for sale) and all its data (historic sales information). Why is the Zillow Z-Estimate based on flawed information when all the real data is already sitting in the regional MLS systems read to use (that means sell) and it's almost without flaw. Is this just too obvious or is there a gaping hole in the business plan that doesn't leverage that? There are ways to tie in even to Redfin and those like them (don't stone me for this!).
Why did it take Point2 to create the first national MLS, when REALTORS have had the MLS system in place for the longest time - it's an embarrassment if you ask me. I'm not sure, but I'd guess it's still not too late to partner with them to do one or both of the two themes above. At least that would be going with a proven winner that seems to have a plan, since I think they have well over 100,000 real estate agents now in the US and Canada, who get a lot more from Point2 for their money than they seem to get from R.com.
R.com leadership is instead taking that site and information the way of the Detroit auto manufacturers and the steel industry leaders of a generation before them. What both of those industries have seen is that by the time they got (or get) their act together, the world long ago passed them by and they can never regain what they were, ever. The NAR is the largest trade organization in the country, but it's strategic technology partners seem to be taking it the way of the dinosaur rather early on in this "battle" for the internet solutions to residential real estate, while all its members sit here on AR and elsewhere night after night carving out their own niches all alone because their leaders have left them to the wolves.
PS - late add: I just read Lenn Harley's recent post on the now-banned use of the phrase "MLS" by REALTORS who are members of the MLS they are effectively promoting when they put an IDX link on their websites. This is from the NAR, not R.com but in this case it's effectively the same issue...guys you are going backwards, not forwards. :(
