Don't count Google+ out just yet......
Google+ is opening up. The service that the enthusiastic and curious once begged to join is now open to anyone with a Google account, except those unfortunate Apps users (what’s up with that?). Users new and old also get to play with plenty of new desktop and mobiletoys to remind them what was exciting about G+ in the first place.
New APIs even let developers in on the fun.So what’s new? For starters, Google’s finally adding the biggest and most-requested no-brainer of all: search.
As you can see from the photo, in the search box that once found only other profiles, users can search over “everything” (i.e., the web), “people,” “Google+ posts,” or “Sparks” (the lightweight Google News front end embedded in G+).
Results can then be filtered by “most recent” or “Best of.” The algorithm determining “best” search results in G+ is unclear, but it’s likely some combination of best keyword matches, posts by users in your circles, plus +1 upvotes and/or reshares.
