We have the tags rss (x10) and rss-reader (x5). As the focus of our site is neither in developing RSS Feeds, nor in recommending good ones, nor in trouble-shooting the feeds (which again would belong to the development category), this leaves issues with RSS reading apps -- so both tags, in relation to our site, must be synonyms (correct me if I'm wrong).
Hence I suggest to merge the two, making one of them a synonym to the other. I'm totally free to which one should become the master :)
