Since it's the mood for today - people seem to be looking back on the year - I noticed Michael Arrington looking at Companies I’d like to Profile (but don’t exist)” which he wrote last year.
He noted cheap online storage - which has come down quite a bit this year but is still not where it needs to be. It's more than that - I tried AOL's free XDrive and found it was too slow - did not work well enough to be useful - so the online storage needs to improve both in size and quality (bandwidth too). Looks like a commentator mentioned http://www.megaupload.com/signup/ (that's more storage than on my laptop right now)!
Portable Reputation management seems to be a good thing that RapLeaf implemented - but I would think it's way too hard to enter in the information (since you don't need to do a transaction - and EBay is collecting that data using transactions that happen). Micheal also mentioned Kritx.com as a decentralized review aggregation service that would be nice if it really worked - and had a wider selection.
That's about all I saw out of his article that stood out to me - I wonder what he's going to look at this year?
