In trying to figure out how to invite/add/follow gillum on g+, I just realized that since we have both a personal page and biz page, there are different 'circles', 'groups' and 'communities' for each page. Somewhat similar to the FB concept, but I didn't quite get that before.
Another thing I just did was to be on G+ and do a search for (my region)bed and breakfast. Up pops a ton of my posts I've shared from by blog. They also come up when I do a search for just my region (no b&b in search). So, that has to be a good thing. I don't think that many people are doing searches like that in g+, but who knows, it might actually catch on one of these days.
I think also those posts get a bit more clout on the organic listing of a regular google search.
