@peakd: You do not need to put peakd as a topic tag ... there is no real benefit and the post is not about PeakD.com so there really isn't a reason to. We are likely the only account to search for posts with the topic tag peakd so it really doesn't benefit you much we suggest you use that space for another topic tag that will help your post more and is more related to the topic of your post. I hope this has been a helpful educative comment.
