I’m not sure how many people saw the news that Google Spreadsheets can now be edited by anyone, but the concept of a a wiki-style spreadsheet caught my attention. You now no longer have to “invite” people in order to have them contribute and edit a Google Spreadsheet.

With listing syndication hot on people’s minds of late and syndication announcements common, I thought there would be value in having a place where listing syndication is transparent in terms of which brokerages and vendors are sending listings to which portals. Being the geek that I am, I decided to take it upon myself to create a wiki-style spreadsheet using Google Docs and see if those in the industry find the document valuable.

I separated the document into three sheets — one for marketing/syndication vendors such as Postlets and Vflyer, one for website vendors like z57 and Point2, and one for real estate brokerages.

I’ve started the spreadsheet by adding some of the vendors and brokers participating in Zillow’s Listings Feed program, but feel free to add to this spreadsheet with any additional information you have about vendors and brokerages syndicating listings, or portals receiving them. If there are other pieces of data that you think should be tracked, feel free to add columns or sheets to the document.

You can also embed this spreadsheet into your blog if you want to.
