My opinion is I would rather spend any time and/or money on something that has a proven track record and is there for the intended purpose and which also has a far higher success rate than the alternative you endorse.
If something gives me a markedly and higher percentage return compared to an alternative I'll go for the higher return option. That doesn't mean I have all my eggs in one basket, but it does mean I haven't any of my eggs in a highly questionable and suspect one.
I'll stick to google and various other search engines that have picked my site up. I find Google extremely easy. My site is top of google for a number of relevant search terms and I do very very little SEO work on it. There is a great deal of drivel spoken about google, I think to try to encourage individuals to participate and take it up, but a lot of it is unnecessary rubbish. Ive been up there top one/two or three on google for 3 years or so and spend about 1 hour a month on average with my site's SEO, if that. Its not even to 'do' SEO, it's more just to tinker around with a bit of text or an image or so, nothing more. I get probably 5K+ a years work from it I guess.
Im currently trialing Dreamweaver, I have the 30 day trial version. Not sure whether to go for the full £350 version or try to get away with the student/teacher one for £120.
