Something thrown together in 48 hours is not a startup; it's a website. It might be able to turn into a startup over time, and I think that would be a far more interesting statistic: how many of these "startups" are doing anything after 3 months?
Interesting fact: On quick count 14 present and former Skype staff contributed to 6 of total 16 Garage48 teams. Skype has had a great effect on Estonian startup and development culture.
All of this during a weekend, where they basically had to use all of their contacts and networks to get external people into work mode - and succeeded in that. So in addition to more technical software hackathons, events like Garage48 give also a lot of experience in other areas. It's correct to not call them startups, but startup seeds (startup idea is not correct either, as the events are more about execution than pure talk). May be some of those seeds will blossom or mutate into new lifeforms.
Is it useful? It is more useful to me than most little websites, but by no stretch of imagination is it a startup. A very minimum viable product at best.
Seriously though, as a small 4-person team they developed an impressive mobile + Facebook mapping / events / social application that can be tried out in many revenue-generating businesses. What they need to do is experiment, iterate, get mentored and find their way. There are so many opportunities where they can grow. Using mushrooms as an example does not mean that's what they actually want to do for the rest of their lives :)
If they were valued at several million, then yes.
One of the projects on the other hand made a lot of fun out of funding/exit bubble, making it their key theme: their only goal was to exit by next Friday. The first thing they did was list themselves for sale on an auction site. One of the VC's on the jury actually made a 50 cents bet on them, raising it from previous 40 cents ;) Having fun is important, not all things are dead serious.
Let's also not forget, that if the people are great and team works well, many of the startups find themselves doing something completely different in 1-2 years time. You just have to get started and experiment.
