Extension:WikiGrok/Lessons learned

Lessons learned from data

 * 3x the number of unique responders as mobile editors during test period (4.5K editors, 12.3K WikiGrokkers), even with WikiGrok on sample of articles & users
 * 1.5x better clickthrough than 2014 Fundraising full-screen mobile banner
 * Using the same design, on May 5th we prompted 6.25% of our users to opt into the beta site. Beta opt ins jumped from 2.5k a day to almost 90k a day. Reduced percentage in bucket to half and reduced to 40k however over time these opt ins decreased. Shows that this translates to things other than Wikigrok.

Wikidata (technical)

 * Still remains difficult to do things cross wiki/cross url e.g. get description, get image, save data. Personally I believe our API endpoints should be able to talk to all our backends without resorting to CORs.
 * Wikidata API is not as flexible as it could be. To save a list of infobox claims for example, you have to make an API request for each claim. Should be possible to do this in bulk.
 * When querying images, thumbnails are not provided making it difficult to render images that are stored in wikidata (see T76827)
