Hello there Karen!
Hope all is well with you............
Loved your blog - good luck with winning the "romantic dinner for two"! (If you win - Save me a chocolate covered strawberry!)
I do spend most of my time (in the wee hours of the night ) interacting here, on Trulia, for all of the reasons you delineated in your blog. I have received a number of leads from responding to questions, and in response to listings posted here. The layout makes sense, and is easy to navigate.
But - to answer your specific question for this thread - my second runner up would be Zillow. I am also active there. I sift through the questions that deal with consumers questioning their zestimates and other technical aspects of the site, and try to separate out the actual consumer questions that I feel I can respond to. Each site has its own distinctive flavor.
I also occasionally stop by Active Rain, but more often to read what others have posted, than to post my own blogs. Some of the blogs there can be very informative - some are amusing and witty.
I float in and out of a number of other sites as they come to my attention, but the above 2 are where I can usually be "found"!
That's it for me, as far as interacting on real estate sites.
As far as the consumer's experience in searching for information, from my experience, I see Realtor.com, our Garden State MLS site.... and my own Prudential site as the most active in regard to leads I receive.
Have a great day!
ps........ based on what has been said below - I'll have to check out Rismedia more closely!
