takes a step away from the heavily textual interfaces of Delicious and Pinboard, bringing a more visual layer to the experience while remaining focused on bookmarking. I haven’t used it personally yet, but it’s a Web-based service with an emphasis on putting a face to your bookmarks’s names, so to speak. It’s free for now, and I’ve seen it appearing lately as an option in some third-party clients such as Reeder.

is probably the next best alternative to Delicious, though its approach is different in a number of ways. Evernote is billed as “your digital brain,” and the Web, desktop, and mobile clients the company offers are designed around managing not just bookmarks, but PDFs, task lists, images, and just about any type of file, too. Though Evernote’s feature set and, by extension, interfaces are different and broader than Delicious, you gain stability in the form of service longevity (Evernote as a company is close to profitability) and popularity, as it, too, is supported by a variety of third-party apps and even has a couple of dedicated third-party clients, despite the home-grown free ones. And speaking of price, Evernote offers a free plan with a generous amount of features and monthly upload quota, as well as a paid plan with useful perks.

is another “digital brain” style app that is geared towards managing bookmarks other types of information. It offers only a Web-based client on traditional computers (though it’s pretty slick, and better than Evernote’s), but the company makes dedicated apps for the iPhone, iPad, and Android OS. Springpad is free right now, though I imagine it will offer some kind of upgraded, paid plans down the road like Evernote.

Before we get into Mac-only bookmarking apps that don’t work or sync with a Web service, it’s worth pointing out that Delicious has had clients and utilities on the Mac for ages, such as Sci-Fi Hi-Fi’s , Code Sorcery Workshop’s , Shiny Frog’s , and a handful of add-ons for Safari and Firefox. I expect that some will add support for Pinboard and other Delicious competitors, and Delibar for both Mac and iPhone adopted Pinboard some time ago. In fact, Delibar has been my tool of choice for a couple years now, as it’s a great client for bookmarking, searching, and sharing your bookmarks via e-mail and Twitter.
