I am keeping an eye on Aaron Parecki’s #Indieweb Reader too.
I am using Inoreader and love the ability subscribe to a feed. I therefore store my OPML on my site. This allows me to add and delete feeds, as well as maintain a permanent backup. The only catch I have found is that the feed does not seem to auto-refresh, so if you delete a link from your blog and therfore your OPML, then you need to remove it from Inoreader too.
