i would love rapportive to have some kind of settings, so that i would be able to specify the order in which the supported sites are searched. (and possibly sorted on display in the rapportive panel, but it is not necessary)
or at least have a chance to set a preferred source for the profile pic shown for a contact. i am using the "disable" extension which prevents fb, twitter and google from tracking me (or at least i suppose so :) ) and with this extentension enabled i can't see a contact's photo in rapportive if that photo have been obtained from facebook or twitter - there is a blank space (however, latest status updates etc. do show up all right).
another motivation for this suggestion is that my friend has a twitter profile pic that i really don't like :) and i would like to have a way to tell rapportive that i want to see a picture from another service - or, preferably, my own from my contacts.

otherwise rapportive is great (i just regret i can only code in java - i suppose you don't need someone who will "learn ruby, jquery and scala asap", right? :D), glad to see you are working on the "merge info for several email addresses into one profile since it is the same person" feature. keep up the good work!
