Zooomr

Zooomr was created by a 17 year old – in 3 months, and TechCrunch see it as a potential rival to Flickr, with improved features. Zooomr (currently off line due to massive interest, sparked, no doubt by having been slashdotted) offers the user the ability to have a variety of metadata – including audio. Audio can’t be recorded online (yet), but has to be uploaded.
It’s also got some inbuilt intelligence – if many shots are geotagged with the same location & date tagged with the same date – it assumes that they are all the same event, regardless of who posted them.
