I’m running it now on my old gmail.com account. Last night’s export of my GAFYD account was 8.3gig – so it gets a lot.

I’m using ttrss. It’s open source and you can self-host it. It can import and export opml files. Feedly was pretty, but I’m not making the mistake of depending on a company again for this sort of thing. ttrss needs a fair bit of work (for one thing it’s written in php), but it’s functional enough to get going. And it supports a slew of front-ends.

But you only have 10 more hours or so to do it.
