1. Top 10 Semantic Web Products of 2008

Note: the products listed below are in no particular order

1. Remember The Milk: Australia

Remember The Milk, the Australian startup that gave us our favorite task management tools, began when Omar Kilani, Emily Boyd and one stuffed monkey got together in 2004 with a simple idea. The idea grew and in 2005 they launched Remember The Milk.

RTM has seen enormous growth over the past couple of years. By October 2006, 100K people had signed up for the service, 200K by May 2007, 500K by March 2008, but it is only within the past year that RTM has had a significant impact on Web users globally. RTM now boasts over one million users, was named one of CNET's Webware 100 Award winners in April, and in May ReadWriteWeb readers chose RTM as one of their favorite Web apps. More recently RTM created a gadget for Gmail and an application for the iPhone, pushing its reach further still.

2. Afrigator: South Africa

Afrigator is a social media aggregator and directory for content from the African blogging community, similar in many ways to Technorati. Anyone in Africa with an RSS feed can use Afrigator to index their content and market it to the world.

Launched in April 2007 (alpha), Afrigator has seen a steady 25% month-on-month growth rate, launching beta in November of the same year. In September 2008 MIH Print Africa acquired a majority stake in Afrigator, giving the startup some breathing room to work on their new project Adgator, Africa's first ad network. Currently tracking 4159 blogs across the continent, Afrigator is a great place to find content from the "Afrosphere."

3. Zoho: India

Zoho is an Indian startup that offers a number of office tools, project management software and CRM solutions. It has made serious advances with its office productivity suite during 2008, reaching a milestone of 1 million users in August this year.

At the beginning of 2008, Zoho updated Writer to include support for the DocX file format along with several other features. In April, support for Visual Basic compatible macros was added to Zoho Sheet; macro record and playback rolled out four months later. October saw Zoho Mail emerge from private beta to being publicly available, offering at the same time offline support via Google Gears.

4. Netvibes: France

Members have created more than 50 million start pages spread across 200 countries on Netvibes since its launch in 2006. Available in 76 languages, Netvibes was named one of Times Best Web Sites 2007; but this hasn't dampened the team's enthusiasm to make Netvibes bigger and better, as evidenced by the launch of Netvibes Ginger in April 2008.

Ginger is a social version of NetVibes that allows you to share your new content from Flickr, Facebook, MySpace, YouTube, blogs, etc. with friends; it also lets you follow the digital life of your friends. In November, Netvibes added a feature that allows content to be shared via integration with Facebook Connect and Twitter.

5. Dopplr: Finland / U.K.

Dopplr is a startup that lets you share travel plans with your friends, and "highlights coincidence," giving you a heads up of which friends will be in cities you plan to visit. While the company has only been around since 2007, it has big name backers, and according to Compete has shown significant growth.

Last month Dopplr launched its new city pages, which include creative commons images automatically imported from the 'interesting' tag on Flickr - to provide a visualization of visitor activity for cities within the Dopplr database. If you're not using it yet, you soon will be; we think Dopplr shows plenty of promise.
