Sure, just talking overall. I see this trend starting on HN recently. I have seen few times when cool projects got hijacked even by owners of different, similar startups. Thus the comment. Good job btw.
In my opinion it depends. Here we are talking about really the same idea, and shariff is something I already used. It also is a few steps further, it has a backend to get vote counters and plugins for several frameworks, like Serendipity, Drupal and Wordpress (now, that is something which might have stolen the spotlight, and I opted to not mention that here).
But no, to your question, I don't think it is a new phenomenon or unwanted to mention related projects in comments. That's why I did not even consider that it might hurt op, thanks for chiming in. But yes, shariff should probably have its own thread, the ones I found are old and did get no attention. I'll re-submit it.
