I'm afraid I don't believe you. The result of submitting to 20,000 directories would almost certainly be that your site would be dropped from google.
funny thread started by a newcomer to Dp with 61 posts. from what i've seen your website has PR 3 so that makes me to write: 1. you're a funny guy 2. you don't see too well 3. keep on dreaming
I think you people are taking his 20,000 number way to too literally - it seems like an awfully round number to me - let's say it was a large number of directories
you say its easy then you said its hard work. i got my one site from PR na to PR 4 in less than 2 months before the update.
It's four months (not days), which appears to be far more reasonable considering he/she hired a SEO company to carry out the job.
20k isnt that unbelievable if you use article directories as well as web directories, i got slightly more in the same timeframe.. But getting PR7 by these means is highly unlikely unless your listed in the highest levels of Yahoo and DMOZ.
I won't be able to do such think. I have other works to do, family to spend time with. I don't think anyone can do without a software.
