I usually have about 90 articles in my Instapaper, and I’m OK with that. I get around to articles a month after everyone stopped talking about them. I look through my queue like it’s a ten-page diner menu, ignoring certain articles for weeks until I finally decide to read or delete.
It could be worse; once I had 500 unread articles. But if your reading list bums you out—if you wish you could declare bankruptcy on Pocket or Instapaper—then you should try the new competitor, Reading Queue.
