In the UK, we have Crowdfunder.co.uk, Pozible.co.uk, Sponduly.co.uk, Sponsume.co.uk, Slicethepie.co.uk and WeFund.co.uk to name but a few. Oh and now PleaseFund.Us has thrown its hat into the ring. Given that all of these sites are doing the same thing, I think that it is easier to eliminate the sites for their failings as opposed to choosing them on their merits. Really and honestly, there is only one site that has made it work and that is Kickstarter.com, which is why they have 500,000 members and have 400,000 people that follow their every tweet.
