Comment articles

It’s never happened as yet, but I was wondering what my response would be if someone wanted to write a Comment article about a Mol Ecol paper, but wanted to remain anonymous. The logistics would be quite easy, but the ethics are much harder.
Are Mol Ecol papers really so perfect that fewer than 1 in 100 currently get a Comment? I doubt it, which implies that there are probably a lot of issues out there being raised and discussed in journal clubs and over coffee tables that never come to the attention of the general readership. Would allowing anonymous Comments increase the number of these that we receive? Would the quality nose-dive? Other people I’ve mentioned this to are sure it’s a bad idea, but I think it’s worth pondering…
