Has a friend ever sent you a link that you swore you were going to look at - only you never did? If you're anything like me, it happens more then you'd like to admit. There's so much great content on the web and only so much time to spend absorbing it all. Currently, I use to solve this problem. I add it to my bookmarks and apply a "read later" tag. It fits most of my needs, but sometimes my "read later" items get lost with my other links. Wouldn't it be nice if there were a service that addressed just my need to save my "read later" links? Leave it to , (one of my favorite blogs to keep up with social media and new developments on the web) which recently compiled the . The services range from Delicious clones to simple web apps and browser . Most of them, I wouldn't bother with, but a few make the cut. Firefox plugin that features RSS capability, offline and multiple computer syncing, plus the ability to add your saved links to other social bookmarking services. My favorite of the bunch. The coolest feature that List Mixer offers is that it automatically trashes links after they've been stored for 30 days. Because lets face it, if I haven't read it after 30 days - I'm never going to get to it. What I like most about Instapaper is that it takes a minimalist approach while still offering some pretty powerful features. You can use it online, on your phone and offline - plus the interface is about as simple as it gets. These days, you can find a service for just about anything on the web. What do you use to keep your bookmarks and "read later" links organized? If you get a chance to try out any of the link saving services, what were your impressions? Are they a necessary tool in today's digital landscape?
