I spent some time browsing the Givealittle site while eating my lunch today, and I'm struck by how great an idea it is.
JD from Mindscape posted about how they built the site, which is of course how I ended up there :)
When I've donated money in the past, or wanted to give a gift of donation for a wedding, birthday or Christmas, I've always spent ages on Google trying to find the project that 'fit' with the recipient (Are they religious? Do they like animals? etc). Givealittle lets you browse a whole bunch of charities on one site, and even give vouchers which let people choose charities of their choosing.
There's other features of Givealittle which are good news for givers and charities too, reduced costs of transactions, transparency over where the money is spent, collation of all your receipts so that tax time is easier and more.
A fantastic idea, and a site that I plan to use this Christmas.
