SocialSpark.com - Will it be relevant to the Real Estate Industry?

I'd like to see what everyone thinks about this service. Will it be relevant to Real Estate? The site is www.socialspark.com

The service, as far as I can tell, connects businesses and bloggers. There are two main components to the site:

1) Bloggers - they build a profile and can have others rate them on their previous work or experience (similar to LinkedIn profiles), and

2) Businesses/Services - they post their blogging needs on the site and have bloggers bid to write (market) about their brand or service.

For a lot of us this might seem impracticle, especially since many of us in the Inman community already do our own blogging. But as a marketing consultant myself, I must say that the concept is intriguing. The site is very aesthetically appealing and seems to be very professionally done. I wonder about the popularity it might gain among those who don't have the time or the natural talent to blog effectively? And I know that there's already a marketplace out there for blogging for profit, but nothing I've seen is quite this comprehensive.

I'm curious to hear everyone's thoughts and opinions on this (I haven't actually tried it myself). Has anyone tried it or heard anything about it? What do you all think of the basic concept?
