Farcaster retention analysis. I have analyzed the retention of users of the past 12 months. The users belong to the cohort months in which they first casted. The first image shows the cohort size of each month while the second image shows their retention rates.

key insights- 
- older cohorts have a stronger retention rate than the newer ones but they also have a smaller size
- bigger cohorts have weaker retention
- The cohort of december 2022 has the weakest retention(in the second month) despite having moderate size

Elon musk had banned links to any other social media in december 2022 as a result of which many people fled from twitter,the users who first casted in december might have been seeking an alternate twitter. December has the weakest retention(in 2nd month),this might mean that people who fled twitter didn't stick around.

yup, that will be included in the analysis but a lot of newer fids(as high as almost 8k- could be higher) were purged so this bias will exist in a lot of cohorts.

re: older cohort more retention: iirc the earlier fids who wasn't active were purged, and what's left were the active fids, could explain why the low fids are really active
