I have a problem with 'unreads' and I'm INBOX 0 and I keep all of my phone notifications at 0 at all times. I would do the same w/Google Reader. But; if there was something that kept surfacing old content as 'new', I would disable that feed or work to fix it before it ended up in GR.
I miss GR.
Unless you're on a bunch of mailing lists, I can't even fathom having that much email, much less that much unread email. I'm fanatical about making sure that I'm at inbox zero as much as possible because the 'unread' counter is the enemy. It takes some effort to set up and adjust filters and actually unsubscribe from stuff, but it's completely worth it to have a mailbox that's actually usable.
I do subscribe to things I find interesting but other times they are emails from services I joing. I am now using Office 365 and am being able to keep it much cleaner. All my Newsletters go into a Newsletter folder and I have a Sweep rule to keep the 10 most recent and delete the rest. My inbox is way easier to manage now. And every year I move the corresponding emails from that year into a folder, like "2024" and go through it from time to time. It's being a bliss.
My two gmail accounts probably have way over 100k as I've more or less abandoned them. Google also made the total emails you have in the account less apparent too, I was up to 80k and suddenly my inbox had around "3,000" or so emails.
It's the simplest RSS reader in the world: no badges, registration or download necessary.
I know I could just type it or send just the website link over, but it just feels like more work and I'm not invested enough (ie if I'd generated a link now I'd feel like I invested effort and would definitely open it on the laptop. With just a link...not sure)
