That certainly tends to support my own hypothesis --<br>which is, of course, based on virtually no facts and mostly a lot of<br>conjecture and anecdotal evidence. :-) Thanks, Leigh.

Experian came in and said they could matchup name/email to their database and give us 30-40 more points of data on each record in the db from credit info to salary, etc. And we think Beacon is bad :) I'd argue Equifax is larger than Experian… here is scary… back in my old corporate days, I built a customer/consumer database with about 9-10 million of our customers.

Do they track people's behaviour online and watch every site<br>they spend money on? I doubt it. In fact, I'm pretty sure that would<br>be illegal. As far as I can tell, they do surveys. And surveys are<br>notoriously unreliable. They often tend to show whatever you want them<br>to show. I have no doubt that they have lots of purchasing data and demographic
