I seriously considered to nominate myself and admittedly, vanity did play a role in these thoughts ;) Eventually, I decided against it, and since you kindly asked, this is why:
Having answered a question or two during my time here, I do seem to have some professional experience in different fields of chemistry, like to solve problems using Python and I don't mind to answer questions on "problematic" topics. In adition, I despise rude behaviour, do not argue with crackpots and do not believe in 3rd and 4th chances for pillocks.
But it takes more to be a good moderator! Foremost, it takes time!
In order to fight off the buggers, inspire the newcomers to become regular participants, hang out in chat to strengthen the community, and to keep the site in the great shape it is in, one has to "sacrifice" a significant amount of time, preferably on a regular basis.
Others have understood that too, and I'm glad that Martin has explicitly stated that he is free and willing to use his time for the community.
Fact is that I can't. I simply do not have the time for moderation that this community deserves.
So, thanks again for asking and tickling my vanity, but I have to decline.
However, I'll be happy to fly in to answer some questions and close some crap whenever I can.
