Yesterday, while going through the Suggested Edit queue, I ran into a couple of edits that only changed the links from one URL to "www.mathdotnet.com". The one in the original post does redirect the suggested edit domain name so I rejected it as "too minor" and the edits were ultimately rejected.
This morning, the author of the edits tweeted at some of the people that had rejected some of the edits asking why we rejected them. One guy is replying to him point to the guidelines say that the edit needed to be "substantive improvements addressing multiple issues in the post", which is also why I rejected the edit(s).
So my question is, are those types of edits really too minor? The domain does seem to be more of a permanent link to the project. But by the rules, it seems like it is too minor.
