Most effective lead generation

From Ken Krogue's Blog comes this, '17 Most Effective Lead Generation Methods' which is great.

I believe that the best methods are those that are most Effective, but least Popular.  So look for a low number on Effective, and a high number on Variance:

Lead Generation Method	Effective	Popular	Variance
Executive Seminars	1	8	7
Inside Sales	2	9	7
Search Marketing	3	6	3
Webinars	4	10	6
Tradeshows	5	3	-2
TV Advertising	6	17	11
Email	7	1	-6
Radio	8	15	7
PR	9	2	-7
Online video / podcasts/ rich media	10	12	2
Direct Mail	11	4	-7
Blogs	12	13	1
Sponsorships	13	7	-6
Online Ads	14	11	-3
Other Web 2.0	15	14	-1
Outdoor	16	16	0
Print	17	5	-12

Popular isn’t necessarily good, it just means everyone else is doing it (email for example is ranked 1st as most popular, but ranked 7th in actual effectiveness.)  Take especial note of the degree of variance and whether it is positive or negative.  High positive variance shows extreme effectiveness that is relatively unused or unknown by your competition.
