I've been testing out SyndBuddy since launch, it was slow moving at first but they recently started doing competitions and my signals have started increasing at a much faster rate. Not terribly fast, but I'm now getting 5-6 likes/shares/+1s/etc. per day as opposed to one or two every few days. Still waiting to see if things catch fire a little more, but it's better than nothing, and most of the likes I've received that I've been able to verify appear to be real accounts, with the exception of a few.
