DeclanR covered most of it. The bit I would add on write is below.
Before committing time to the site, work out what the free ceiling looks like in practice.
Out of roughly 80 matches on write, 4 turned into an actual conversation.
The signals that told me most about write:
- Whether the filters on write hold after you reload the page
- How much of write is visible before it asks you to register
- Whether the write match count moves when you widen the radius
