I read a lot of threads that I never post in an likely never will - this makes it difficult to find them.
How? It only moves after you read them, so what scenario are you trying to find them between reading them and them not getting a new post?
The old way, you could read them, but they'd still be there, and unless you plumbed the depths of every new page on /newposts/ you would miss some new posts.
This actually is going to make people miss a whole lot less
, but yes there is a specific use case (re-reading a thread you just finished reading and that has no new posts) that is harder, I just think that this usecase is so much more rare that the net of the read tracking sorting is much more topic discovery and more reading.
But if there are usecases I'm not considering please walk me through them.
Now, where is that robust search feature, like the old forums had?
It wasn't robust, it was broken and whole months were missing. And to avoid that kind of thing and do it right is very non-trivial for us. So search, as much as I'd like to have it myself, is going to wait for other lower-hanging fruit (features like groups that are much easier and have a greater need right now).
