Since I have two productive pen names (and I've just started to recently get back into the erotica game -- but I can't do that on a weekend, so it's moot right now) I've been paying more attention to my author ranking on Author Central. I hate to say it, but I'm obsessed with hitting new milestones. My main name is cruising. It's pretty level, although a recent release has bumped me up into the top 250 for all books and 130 for ebooks. My poor pen name, though. Ugh. I've had big highs, and big lows. I just launched it in October, and it's an ongoing process. I had my best two sales days ever (without promotions) yesterday and today (thanks to a new release) on my main name, but my pen name is down today (by like 6,000 rankings) and I'm a sad little puppet. Who else basks in milestones even though they don't want to?
