prldr.com let's you create lists of links and preloads those lists for you.
It's got a very basic API, so you can use it to create and update your own lists.
I can think of multiple use cases for it. For example: load your twitter feed, scrape the links and display them, load all your rss feeds and display them, open up all links off a frontpage, to preload them.
What do you think? What kind of things must I add to make it useful for you? You might just not like it, because of the iframe technique used, just ignore it then, it really is a very hackerish tool and not meant to be more than that.
It's a neat tool, but I don't know how often I'd use it. Pre-loading the info is neat for twitter, but the additional second or two it takes to copy/paste the info into your app seems like it'd be longer than just waiting for all the pages to load.
Middle-clicking and background opening them in new-tabs is easy enough for me.
There's an API to make the twitter link fetching possible. Was curious how people might use it, think there are lots of posibilities. API is very very simple, just 1 RESTful controller. Hope there will be someone who can come up with a cool application that makes use of it.
Your app reminds me of http://www.flipboard.com/ It's a very cool idea to be sure. I wish there were Flipboard for the rest of us. Maybe that could be an interesting alley to explore.
We're extracting our marketing tools out of earlier build webapps, this will be backendfu, so webapps can be build even faster. This is it for now, later more information.
