I had really liked this plugin. Easy to use. Nice icons. Showed full counts (not just 1K when it gets over 1,000). However, plugins must be maintained. If a problem occurs, then it needs to be resolved - and when users ask about it on the plugin's home page, they deserve the courtesy of a response, not just left in a moderation queue.
Sadly, I had no choice but to remove Social Media Counters. When the Facebook button disappeared, replaced with only the text "Share" (not even indicating the social media site), it impacted badly on sharing of articles. I gave it more than a day - but without even the courtesy of a response, would not consider going back to it.
