Good comments Liz, I agree if someone was appointed by TIC and posted info, it would be make this a much more informative and interesting forum, however, this would also legitimize this open, unregulated discusion. I'm sure TIC fears the lack of control.
Equity, you really haven't told us why TIC is concerned about this blog, and your graphs only show that TIC traffic remains flat while IHB's grew. IHB's growth is perfectly logical as the popularity of the site has grown in relation to the increased press and references as the economy declines. Furthermore, so called declines on TIC's website coincide with anticipated seasonal lulls, your span of data is WAY to short to make even a guess.
Jesus, as a good judeo/christian patriotic, flag wearing american, i hate to beat a dead horse here, but TIC isn't concerned about this site because this site deals with the for sale housing market and TIC's core business model is commercial RE, which, as we have seen, is buffered much more than for sale to economic shifts. Sure, many many negative things about TIC have been said on the forums (i.e. the irvine company still uses asbestos and lead paint in their construction, and the irvine company made me sterile), but these comments are dilluted by the sheer volume and discredited by the ranting and haranguing nature of the posters (guilty!). This website isn't focused on disparging TIc, blog posts by IR are focused on resale housing, even a first time reader would recognize that.
On a side and personnal attack note, the fact that you recommended that a real estate company start a corporate blog and forum would make me drop your proposal into the incinerator and question charging you for the paper i printed it on. RE companies aren't like google, apple or some hip design studio that's constanly cranking out new ideas and looking for some grass roots advertising, RE companies create more traffic, noise and light pollution, changes the beloved communities of old people, and in general participate in many earth destroying activities. The product hasn't changed in a hundred years, and all projects need to be approved in a public forum (at least in so cal) the last thing any RE company is going to do is allow activists another tool to voice their crazy opinions on a legitimized (aka developer run) forum.
