Simple Schedule Appointments has a self explanatory name, and looks quite promising. It's a project by Natalie MacLees and Nathan Tyler. I interviewed Natalie at LoopConf about this, so be on the lookout for the video soon. The plugin looks fantastic, and is available for pre-sale.
Good ideas for the future of data disclosed to plugin authors using the wordpress.org repository:
1) Identify surges of unhappy users reacting to a bad release — and the opposite, happier outcome.
2) Use pageview analytics to estimate total potential user interest and conversion rates.
3) Assess a plugin’s performance with the .org search algorithm, the quality of releases, and plugin incompatibility as well as PHP compatibility issues.
4) Collect significant user behavior data anonymously without phoning home.
5) Just reveal all the raw data with privacy options for individual authors — no interpretive analysis on wordpress.org.
