Fastladder is an online RSS reader that come with a very powerful prefetching function. Its interface is well designed so that users rarely feel any delay. The feeling speed is almost incredible compared to Google Reader or Bloglines, especially if you have a large number of subscribed feeds.
The service sells itself with the copy "1000 feeds in your sight", by which they are trying to say "No matter how many feeds you subscribe, it will never slow down." In fact the developper of this service claims that he is reading 7000 feeds, and Fastladder is made for those people like him. At the moment, I'm reading only 164 feeds--of which about 10 are newspapers, 20 are online magazines, and the rest are blogs--but if I export them to Google Reader, it is already quite stressful to use.
It's free, of course. You just need to go to Fastladder.com and sign up or use OpenID/Yahoo ID to sign in. If you are migrating from another feed reader, you can import the OPML file. There is a bookmarklet to subscribe for an atom/RSS as well. In Opera, I use a keyboard shortcut for subscription,
So that's about Fastladder online. Yesterday I saw quite a stunning news. Fastladder now made an open source version which you can install in your local machine. It acts as a local server that you can open in your browser, and has most of the functions of Fastladder online version.
For windows, there is a one-click installer. How to install is described in their blog. On Mac OS X and Linux, installation is a bit harder. You need to have Ruby 1.8.6 and RubyGems (and FreeImage library for Linux) installed. According to the blogs of people who already tried it, the installation is straightforward, a few lines of command.
As I wrote above, the online Fastladder is (or feels, at least) as fast as many of the local RSS readers already. You might want to install it if you wnat to use it even faster (no time lag even using a mouse), or if you need to read non-public feeds in an intranet, for example.
The open source Fastladder is aiming to work on group sharing functions, full text search, etc, which Fastladder is currently lagging behind Google Reader.
