(1) TOR KB has a page about it [5], which I'll quote here just in case: How many posts per feed do you store? You may only see several dozen posts when you subscribe to a new feed because RSS feeds only contain the most recent posts. However, new posts will be fetched as they get published, and The Old Reader will store up to several hundred posts per feed for any active user. If you don't access The Old Reader for a while, your account will be marked as inactive, and we will only keep the last 10 entries of each feed for you. Shared, commented, or liked posts are currently stored forever. "Up to several hundred posts" is quite vague term, and definitely not enough for long-running sites that publish new stuff often. Second problem is being "active user". There are weeks when I am so busy that I check only LWN.net in tram on my way to or from the work, thus I may be "inactve" (from feed reading viewpoint) even for a month. This makes TOR unsuitable for me after all and this is unfortunate, because I started to like TOR. I noticed that in comparisons of feed readers (almost?) no one is looking at how long the old posts are available, that's why I'm asking the HN community: Is there any free on-line feed reader, similar to GR, committed to preserve old and already read posts, no matter how actively I read them? It would be great if it supports keyboard-driven navigation (with GR-like shortcuts, hopefully) and has mobile apps (Android at least). Bonus point would be possibility of exporting historical feed data.
