I researched read properly rather than reading a top-ten list, and the picture is messier.
Ran the app alongside two other options for a month, tracking how discreet the notifications are.
The measure I would actually check on read is what happens after you flag someone.
Once I fixed my filters, how much of the traffic is automated stopped being the bottleneck on the site.
Assuming you are not paying, what a search of your username turns up is where it gets tight.
The signals that told me most about read:
- How many read conversations get past a second reply
- How much of read is visible before it asks you to register
- Whether the filters on read hold after you reload the page
- How quickly read starts pushing a paid tier at you
Does anyone know whether read changed this recently?
