I mean that period for all sites after the launch coverage, the time where your traffic goes down to almost 0.
Who to meet/who to talk to...should have been done prior to launch.
optimizing text? it takes a while to do a/b testing if your traffic is tiny...same goes for seeing results from marketing campaigns.
updating the blog? that takes a few hours each week.
I mean sure, there is plenty of things to keep you busy, but most of it is just busy work you assign yourself because you are thinking "hey, I'm doing a startup, I should be doing something"
