Far and away, the most popular website, when it comes to storing ‘in the cloud’ bookmarks, is Delicious. It became so popular so quickly, that Yahoo picked them up in December of 2005 for somewhere between $15 million and $30 million.
For those of you who don’t know what Delicious is, it is simply a one stop shop, for storing your bookmarks in one quick and easy location.
Of course with success comes competition, with sites such as Diigy or Simpy and you could possibly even consider Digg or Reddit as well. However sometimes you find your own opinion matters the most, and you’d like to create your own private bookmarking service for your family, friends or maybe even your workplace. That’s where with some prerequisites from your web host, and a little MYSQL knowledge, you can create your own social bookmarking site, with Scuttle.
Scuttle is simply defined as a “Web-based social bookmarking system. It allows multiple users to store, share and tag their favorite links online.” It is an open source product that requires only PHP and a MYSQL database from your web host. After installation, you’ll have a very similar look to what Delicious offers.

Similar to Delicious, the Scuttle system offers tagging with keyword relations, a tag cloud and advanced searching for your own bookmarks, or the entire site.

Just like Delicious, you also have advanced security for protection on your bookmarks.
