`  :Looks like Karanacs has beaten me to it… I don't entirely restrict myself to topics I know—I seem to have done an awful lot of rats lately—but I do generally try to restrict myself to areas I know (mainly civil engineering, music and transport). In general, I find that reviewing articles in fields I don't know is tricky, as so many areas have their own particular conventions. If you ever want me to look at one in future feel free to poke me here—I won't consider it canvassing given that I've requested it. –  `
