For some this means getting info from 3-4 agencies, for others a dozen or more. Some people's comfort level extends only to agencies in their own state, others can take advantage of more opportunities. If traveling parents and agency personnel take stuff directly this doesn't seem to happen. Well, happy people don't make noise, anyway. Now, with the internet, there's almost too much information, and a lot of it is highly suspect.
Many wonderful agencies have good, attractive sites, and many sleazoids do too.
I see ICC as becoming even more important in the future to vet agencies, letting people know who's really on the up and up, and who should be avoided. Of course, I have a penchant for licensed agencies, as opposed to liaisons, etc.
