The problem with this approach is feasibility. Some companies like Netflix and Amazon have done some complex recommendation engines, and I still don't think they're processing as much data as an all-encompassing social network data aggregating recommendation engine would.
I believe Reddit was at one point going to try and create a news recommendation engine but found it impractical as the number of users grew. The number of permutations for what people in just one user's network like and dislike is staggering.
- joeyo 17y agoGiven that it's presently possible to offload data processing to a number of cloud-based computing services, I'm not sure that we should be afraid of the computation cost. If you are willing to make some assumptions about independence (for example) you can do a lot of the computations in parallel. A more subtle issue would be how much the use of social net data would gain Amazon or Netflix over their current recommendation engines. I suspect it would be quite a lot, but that's just a guess.
