I haven't logged into Google Plus in a little, so I cannot tell if this is a new feature or a result of my infrequent usage - nevertheless, I was taken aback by Google's new Trending on Google+ module... which looks exactly like Twitter's. While it is interesting to see that the topics are related (ie Junior Seau, NFL), I was most interested by the use of hashtags on Google. Within my Google+ network, I have not seen hashtags used with any regularity (whereas they obviously are part of the Twitter culture) - I also would have assumed they would relied on real-time search and trends to populate the list.
