I thought 3rd party access has already gone, with the exception of a few apps like narwhal.

Is old.reddit officially being killed ?

I am starting to. Still browse Reddit occasionally for the communities that are not in here yet.

Reddit as a whole seems a lot less populated. Example, the r/android sub is nowhere near as active as it used to be.

Nice growth, looks to be slowing down a little - I wonder how much is related to the poor performance last few days
