I'm still in the middle of picking a replacement, but so far I have been a little disappointed at some of the suggestions put forward by other blogs. Some of these fools threw together a list of apps like Pulse, Flipboard, Google Currents, and the like, none of which meets the needs of the average Google Reader user.
Those apps are all intended for entertainment reading, not for use by hard-core news junkies like myself. The hard-core user needs a way to pack as much info on screen at once. We are not out to be entertained; we want to get as much info as possible.
I follow 1900 feeds, and while that is a little extreme I bet that anyone who follows more than 100 RSS feeds has the same needs I do. Rather than suggest useless apps, I am going to list the ones that I plan to test:
Opera (this web browser has a feed reader built in)
Update: And here are a couple late additions:
Feedly looked like an early contender,and the developers behind this app had even been working on a setup called Normandy that operated completely independently of Google Reader. But I've tried it and I don't like the UI. First and foremost the UI designer thinks gray text on a gray background is a good idea, but I also don't like Feedly because it defaults to the same prettified and information-poor layouts found in apps like Flipboard, Google Currents, etc.
Feedly is rapidly growing to be the leading replacement for Google Reader. This service has responded quickly to the influx of GR users and added features, viewing modes, and defaults that might fill the needs of a hard-core news junky.
I have given up on using the rss feed reader option in Opera. It is frankly an ugly and minimally functional cobbled together afterthought that doesn't offer nearly the features viewing modes, or functions I need. Plus I think it gave me a migraine - twice.
CommaFeed is a relatively newcomer to the market. As of late May 2013, this service is still ramping up from its first few thousand users while adding features as fast as it can.
Bazqux is an established but relatively unknown news reader. It is nearly as feature rich as Google Reader was and can support a thousand or more feeds. This is a paid service and it does not currently have any mobile apps.
FeedsAnywhere is a very mobile friendly, free, durable news reader that works well on small screens. It too can support a high number of RSS feeds.
I have not tried all of the rest. Have you? What do you think?
