6. Maxthon: China

The browser market has seen many changes in 2008, with the introduction of Google's Chrome in September, Mozilla's Firefox 3 making the Guinness Book of World Records in June, and the slow decline of Internet Explorer as Firefox gains momentum. In Asia however, there's another browser making waves. Maxthon, according to European web metrics company Xiti, is creating problems for its main competitor Firefox. It comes as no surprise then, that Mozilla recently released an edition of Firefox specifically for China.

Maxthon is a browser created in China and reported to be the second most popular browser in China today. While it doesn't show up as a contender in most market share reports, it has had a staggering 174 million downloads at the time of writing this post. Using Internet Explorer's rendering engine, Maxthon has over 1,400 add-ons, proxy switching capability, aggressive ad blocking, split-screen browsing to name a few of its innovative features. We said it two years ago, and we'll say it again: this is one to keep your eye on.

7. Xing: Germany

LinkedIn has over 30 million members, and according to Compete a 179.6% year-to-year change that beats Xing's at 137.6%. It is important however, to note the financials, something we analyzed back in March this year, which may not be completely in LinkedIn's favor. The data of particular interest concerns user engagement; visitors to Xing stay an average of 43.4 minutes on the site, while visitors to LinkedIn stay an average of 7.8 minutes - a whopping difference of 456%. We think Xing has made some good choices this year, especially the recent hire of Stefan Gross-Selbeck, as reported over on ReadWriteWeb's Jobwire.

8. FreshBooks: Canada

FreshBooks, the Canadian online invoicing, time and expense tracking service for individuals and small companies, has been showing steady growth over the past year according to Compete, and claims to have over 500K new users since May 2004.

We compared FreshBooks with other online accounting services in August this year, and decided it was easy to use, includes a host of useful features, has an active forum, and offers benchmark data by industry to its users. More recently, we looked at FreshBooks Report Cards which provide an insight into how your business fares in relation to other businesses in your profession. Selected as one of the PICK 20 top Web 2.0 leaders in Canada in September this year, we think Freshbooks deserves a mention here too.

9. Mixi: Japan

Mixi, Japan's biggest social network (only available in Japanese) was previously known for its closed platform. No more. In August this year, Mixi announced that it is acting as an OpenID provider - therefore bringing the global OpenID to millions of Japanese users.

While Mixi is not acting as a relaying party yet, allowing users to login with OpenID from other networks, the functionality of Mixi user profiles has now increased dramatically. According to the blog Asiajin, this opening up is pretty radical for Mixi standards.

10. Wuala: Switzerland

Swiss startup Wuala offers an unusual online social storage system: it uses the disk space of other members' computers as part of the cloud. Wuala launched in August 2008 - making it the youngest of our international products.

Wuala differs from our other favorite online storage services in several ways. The advantages of this type of storage include no limits on file size and bandwidth. However the main disadvantage is that regardless of the AES-128 and RSA-2048 encryption, the idea of storing data on machines scattered around the world won't appeal to all. Still, with 28 million files uploaded as of writing and growing by the minute, Wuala is definitely worth watching.
