Barry Hunter, Top Contributor in the Google Maps & Places forums and Maps expert, took the matter of the missing RSS feeds for the Places forum into his own hands and crafted these feed URLS.
And these feeds should work in Google Reader only – probably wont elsewhere. Right click and ‘Copy shortcut’ then paste into the new subscription box in GReader:
The “msgs” (new messages) feed is with an entry per post, and “topics” (new topics) is just for the first post per topic.
Update: John Muller just posted this RSS feed for the forums on Google +
.. just swap out “webmasters” with the appropriate part of the forum URL. The “topics” feed is per thread, the “msgs” feed is per message. The downsides to these URLs is that the body of the post is cut off at a certain length, and that you can’t look at these on a per-category basis (it’s awesome that Barry’s feed is per category).
So here are the two feeds (not sure the difference between the two). And both seem to require Google Reader:RSS Feeds To Google's New Places Support Forum Courtesy of Barry Hunter by Mike Blumenthal
