Watch out for online fraud with Garlick. I expect this type of site has huge potential with the direction things are going – you just can’t expect the banks to look out for your identity these days.
Tape it off the internet has potential – would work quite well with an iTV.. hmmm 
Property search engines How on earth has it taken so long for this to happen? its such an obvious idea!
WeHangHere Not an entirely new idea, but a new twist.
Mobizines Genius idea – kind of like a more interesting google reader as this is actually stuff you want to read (and probably do all ready).
SelfCast YouTube but with a focus on the UK. More culturally relavant videos or just more pirated UK media..?
TrustedPlaces Find Places that people like you go – a reverse WeHangHere (see above) if you like.
horsesmouth – This an interesting concept and probably a unique idea – mentor or be mentored on subjects that a relevant to you and where you know a lot/or not.
CrowdStorm Social Shopping for a 2.0 era – this could really work for online retailers if used wisely.
