I write reviews because I felt like I could after one day. I don't take requests, but I do polls so I don't get burnt out on what I should do next.
I have a lot of misspellings because I usually write in WordPad, or another program that doesn't have a spellchecker, usually either because it is easier or because I don't want some program nagging me about some word that isn't in it's dictionary.
Do I have a set schedule? Yes, I try to do them every Friday, or just on Fridays in general.
Why don't I take requests? Multiple reasons. Partly because I don't want to bother with rejecting because I don't have a game, partly because I don't want to have someone's request looming over my head, and partly because I just don't do them. I can't put it more bluntly than that.
