I only ever really browsed Reddit with Apollo and I monitored the situation somewhat. I feel like the subs that could migrate easier (more techy, more text than pictures) stayed closed the longest or permanently. The ones that can’t really (like those more picture streamy ones as the sfw porn network) were open again fastest from what I remember.

So depending on interest it could have felt way shorter or longer.

I am still missing some of the subs I liked, but I don’t expect some of them to actually pop up here.
