The top 25 UK web 2.0 start ups

You could argue that most social networking sites are basically dating agencies for people who don't want to join dating agencies. But this actually is a dating service, with Web 2.0 features. Besides the usual profile stuff, the site claims to learn your likes and dislikes and suggest likely dates based on that, rather than just going by a questionnaire system.

10. Mobizines
"Mini Mags on your Mobile" is the sell-line, which just about sums it up. You download the Mobizines reader application to your phone, then sign up for various mags, to get a regular supply of content. Parent company Refresh Mobile has signed up an impressive stable of media already, including the BBC, Glamour magazine, Holy Moly and GQ. If all the mobile operators get round to scrapping data charges, this could take off. Read an interview.

11. Ebeebo
Matchmaking for jobs, giving recruitment a Web 2.0 spin with a service matching jobseekers with positions. I like the way it moves away from CVs as the basis for any application, the fact that the search function is pretty powerful, and especially its eBay-style ratings system, which is a novel touch for a recruitment site.

12. Sleevenotez
Having finally got into Last.fm last week, I'm really taken by Sleevenotez, a website that bungs real-time information around what you're listening to on Last.fm, including biographies from Wikipedia, photos from Flickr, videos from YouTube, discographies from Musicbrainz, and lyrics from Lyrc.com.ar. They call it "virtual packaging", and while it won't stop vinyl snobs banging on about the commoditisation of digital music, it's a slick and useful service.

13. SelfcastTV
Originally pitched as a "Brit YouTube", with the theory that people will be more likely to come back regularly if they're presented with more culturally relevant videos (I think this may be code for binge drinking and football). You can probably argue with that premise, but there's enough in SelfcastTV – including its relationship with sister firm Blinkx - to make it worth watching in 2007. Read an interview.

14. Yuuguu
Sounds a bit like posh pronunciation of yoghurt, but this is actually a remote-access application that lets people see, share and take control of each other's screen and applications, with live messaging alongside it. Its promise to be easy to use is the key thing here: if you really don't need 20 years' IT experience and a bum-bag/utility belt to make head or tail of it, this could be great.

15. Mobango
I'm not quite sure what to make of this mobile sharing service. It provides you with tools to convert videos, music and photos to mobile-friendly formats, then 1GB of space to store them online AND share them with other people. The top-rated games available for download are all commercial games, which seems a bit strange – do the publishers get paid for these downloads? – but the overall concept is a fun one.

16. Horsesmouth
Another social networking community, but this one has a strong angle – it's built around mentoring. So the idea is you can sign up to find a mentor, and get their advice on your lifestyle, job or whatever. Or you can become a mentor yourself, sharing your wisdom with other people. I wonder how the commercial model will evolve – will there be rewards for the best mentors, for example? One to keep an eye on, as it's still very new.
