Hello everyone, Thanks much for your feedback! One of our ideas behind publishing these details was to invite inputs just like these that we could feed back into to the system to improve our processes.
I'm going to study the details in Anatoly's first mail to verify those things for myself. But they are not necessarily because we mis- evaluate the ranking, but because of certain other troubles we've been facing with the directory listings itself. Some of these are beyond our present control, but we've already been working on isolating some of those problems, and you should see better results soon. We liked the idea of also taking into account the time spent on each app by users. That, adjusted for the latency in renderings, would certainly be a good metric too, and we'll work on these lines soon. ~Prashant On Sep 1, 3:58 pm, anatoly <anato...@gmail.com> wrote: > also: > You should count the time spent on the app. > It is possible 2 apps have the same ranking specified in the blog > post, but users spend 10 seconds vs. 30 minutes or more per day on the > other. > > On Aug 29, 1:55 pm, anatoly <anato...@gmail.com> wrote: > > > > > 1) Suppose the app has many pages, you can either load each page in > > ajax or reloading with parameters. > > ajax is preferred from the user perspective but is not counted as > > rendering, which could be easily faked also to boost the score. > > > 2) Because of recent changes I doubt there is any value for profile > > rendering anymore. > > > 3) Also: I didn't see any weight for activities published.
