The biggest issue for me was a massive, "so what?" I installed the extension and did some searches. A few G+ results, nothing else. Okay, I'll search for things I know some of my friends on facebook have talked about lately. Nothing. Alright, I'll search for "deadmau5". Nothing. What's this? 80 personal results? Sure, let's check those. Hey, a twitter link!... to someone I have on G+.

Really not sure what the authors were trying to prove, here. In the end, I got a snarky logo and the same damned results I would have gotten from Google, anyway. Removed.

Note: this is not a failing of the extension's author; I just went back and tried the same searches with the original script and had the same results. No, I didn't Google "movies" as they suggested, and nor has anyone since 1999. When I google "SOPA" without the script, I get a mix of Wikipedia, EFF, and some relevant links from G+. When I repeat the search with the script, I get the same thing and a snarky logo.

Instead of chastising Google for not including results from networks that don't want their social graphs exposed, these "independent engineers" might want to focus on doing social search themselves. Why aren't we complaining that facebook doesn't include G+ in its search results? Might it be because this entire issue is a tempest in a teapot stirred up by companies that wanted to dominate social search, but were beaten to the punch by a company that dominates (surprise, surprise) search?
