yes 13,700,000... typo... still the point is the same. Millions of results for "security attacks", only a handful of people searching for it.
If "years of experience" counts: You'd have to defer to me --- registered my first names in 1994 (12 years ago), was online for about 10 years before that doing BBS software development, and my experiece with online systems goes back to 1974 on DEC mainframe with 300bps cradle modem connected timeshare tty's. Oh yeah, and I have a print marketing background...
found a FAQ at a different URL, still nothing about what the numbers mean or why they are different from the main inxed "total number of documents".
For the rest of this, I am going to defer to WebWork since this thread appears to be more about buying names for "type-in traffic" than general "find domain name of value" info -- although the two are not mutually exclusive.
