When G+ Profiles first appeared, I recall that public posts had feeds.
Those feeds disappeared. Now G+ is more of a walled garden than Facebook.
Now Jeff Turner has one ...
This site is still in beta so it might go down from time to time. If you have any issues please submit a issue to Github Issues. I had to up the cache to 60 minutes so we don't run out of API calls in a single day.
Here's my (100% public) John Gordon feed via nodester: http://googleplusrss.nodester.com/107785880910936077757.
It renders in GR. Next I'll try using http://ifttt.com/ and Feedburner to turn my G+ posts into something I can own and others can consume. I hope Jeff can make a business of this somehow.
Update: I tried a feedburner version of Jeff's converter but IFTTT didn't like it. It complained "Feed has items without valid urls".
On the other hand, ifttt will share G+ Posts to Tweets using yet another G+ to feed service - Plu.Sr. Looks like there are more than a few of these! Talk about routing around evil.
So here I am on Plu.Sr, where first sentence becomes feed title: http://plu.sr/feed.php?plusr=107785880910936077757&short=true.
From this ifttt creates posts on my unused Posterous blog: http://jgordonshare.posterous.com/ -- but only if autopost is turned off.
I tried this one with Feedburner, but it complained: "The URL does not appear to reference a valid XML file. We encountered the following problem: Error on line 77: The reference to entity "T" must end with the ';' delimiter."
It's just for play at the moment, but it looks like we'll have some options. At least until Google terminates my John Gordon Profile.
I've also set up a ifttt action to http://twitter.com/#!/jgordonshare from my G+ shares.
Next step will be to get my wordpress microblog working. Then IFTTT will create wordpress posts, and that will in turn have a feed and a twitter stream.
