Google has been forcing G+ on everyone in every way they can recently, including the need to have a G+ profile to be able to log in to youtube(along with an extremely annoying name change request), but I didn't expect them to try to hijack hashtags too.
If I was Google I'd worry that hashtags are a twitter thing, not a G+ thing. If I search for a trending hashtag I'm looking for what's hot on Twitter. G+ posts are neither updates(facebook) nor instant(twitter) and so aren't a great place to find trending news.
