In the constant quest for increased productivity, we're always on the hunt of extensions, web apps and programs to speed up the browsing experience. Nextly is one such tool that condenses your favourite sites into single streams of articles that you can cycle between using nothing but left and right buttons on your keyboard.
You can check out Nextly here, where there's a straightforward demo explaining how it works. In a nutshell, it streamlines the process of reading isolated sites and makes it a little faster by binding control to the keyboard.
Pages are preloaded so the delay between hitting a direction and seeing content is minimised, though for media-heavy content it can still lag a bit. Because you're using the keyboard, rather than clicking a link with the mouse, the delay feels longer than it probably is.
If you'd like to give it a test run before signing in (which requires a Twitter or Facebook account), Nextly has Wired, Smashing Magazine and Mashable, among others, already set up. It also works on social media sites, such as Twitter.
I found it was a nice alternative on my notebook, where selecting things with the touchpad can be awkward at times, but I'm not sure how it would stand up to a well-configured system of personalised shortcuts and a real mouse. Give it a go and let us know what you think.
