Josh is deserving of the spot and can fill the spot left by DT. He has been editor for the longest of any of the current editors and has done a great job as editor (if we forget about the hiding of all those RMT questions. :P)
And then we can promote one of our many experts to the spot of Editor, maybe even promote two experts to editor, seeing as we are now on the second column of the Special users page (we have a lot of experts.)
We have many excellent candidates for the editor position but the two that stand out most are Halcyonic Falcon and Hex. Both are excellent users.
Halcyonic Falcon has even reached the 10000 mark, the old point for promotion to expert, all of whom that have previously done so are now editors (besides Shx, whose not being on the site has to do with that). While he isn't on as often as someone such as Mew, he still clocks in more hours than DD and is a decently active user.
Hex is also a great user. He is on more often than HF is, as well as on more often than 4S. While he doesn't have as many points than UberPwnage (a user whose swift point rise brings back memories), he has been on longer than UP, and I'm sure users would rather the new editor have been on for more than five months (maybe next promotion round UP.)
