The Answer to The Ultimate Question Of Life, the Universe and Everything is a theoretical solution in Douglas Adams‘ book series The Hitchhiker’s Guide to the Galaxy. The “Answer” is simply “42“. In the story, the Answer is produced using the hypercomputer Deep Thought.
OK, so I have to own up that this crazy book has always been on my bookshelf of favourites. Nuts!
Naturally I had to test out mind42.com! Not sure if the developers know about Douglas Adams, as they say the name stands FOR TWO, which is the minimum required number of people to do something together.
Is mind42.com the ultimate mindmapping solution to manage all your ideas? Well, it just might be. You can collaborate, or manage revisions. Link images or URLs. Make notes or create a ‘to-do-list’. Amazingly, it sports a Wikipedia API – so you can search wikipedia, and attach an article. Would like it to have more flexibility with shapes and lines – but overall pretty interesting.

Well, now I’ll just have to check this out. 42. Love the answer – has bought me time a few times as I’ve been in a corner. Love the books but the movie just didn’t work for me. I love the mice and the planet building place. Would love to get me one of them! Could put it by my holodeck and really do some teaching.
