Good idea!
Also, might be a good idea to list what the expiration time frame is, for instance AA is 18 months, Marriot 24 months, etc. (not sure if this already exists somewhere) Different rewards programs have different expiration dates.
btw, points.com requires 4 best buy rewards (not 5) to exchange to AA and UA.
I'm working on the best buy to AA exchange because i'm 34 AA miles short towards a travel award!
