I was tired of Facebook (still am) and was all set to switch over to G+ back in 2011. It seemed like the new, fresh social networking site and I was excited to be a part of it and help it grow. However, google's decision not to make an app for Windows Phone killed any interest I had built up for their social networking site. It wasn't out of spite or anything, I just do most of that kind of thing with my phone, not my computer so I just lost interest in G+ (and since then, almost everything else they offer). Nice business plan, google.
