FYI, we're trying to keep up with the new releases at this site,
http://www.kdlapps.com/, where we're also collecting reviews and trying to group the apps. E.g. we did a recent list of educational apps (
http://www.kdlapps.com/all-educational-apps-for-kindle/) and will soon add interactive fiction and productivity apps.
If anyone is interested in writing some guest reviews, we'd be happy to post them and cross-link back for full credit of course (I wish we had a budget to pay writers, but it would be a token amount at best). We'd especially like some comparison articles in categories by enthusiasts. E.g. there must be at least 5 Sudoku apps available now. Which ones are the best and why? Or, which of the two Peg Solitaire games would win if they played against each other?
Has anyone else noticed that the release rate has increased a lot lately, with a lot of new publishers getting their 1st apps released? Interesting times ahead maybe...
