Too little time; sleeping when I should be reading and reading when I should sleep.
Mostly English language SF/F, but I occasionally read other fare.
What it means when I rate something:
★★★★★ - This moved me in a way that changed my life.
★★★★☆ - I loved it.
★★★☆☆ - It was OK
★★☆☆☆ - Meh, it was entertaining at least
★☆☆☆☆ - Complete trash (if I dislike something, but it is well written I'd rather not give it any rating. The single star is reserved for the real trash).
Addendum: I will not rate badly written stories by obvious first time writers. If you have managed to self publish your first story and people actually read it, I'm not going to piss on your parade. I'll reserve that single star for your next book (or the fifteenth one for that matter).
Note: I have heaps of books imported from another database where the rating used was 1-6 (dice), so some books are rated higher than I would normally. I'll be adjusting stuff as I work my way thru the list of books (once I have fixed the 300 or so books that didn't import automatically :P)
