More personal pages was actually my point of linking to ThemeFrame. If you look at forum of his main theme Atahualpa and the long threads about "See my site" then some obviously use it to full extend but most are not that interesting. Same goes for most themes which does allow heavy modification. When Thesis debate was on I checked many sites of those who used it (via comments) and went zzzzzzzz. Just not easy to do so there seems to be a market for easier ways of modifying appearance. I have read posts in ThemeFrame forum and it is clear many see it as a way out so to speak. Like other tools much output is decided by interface, does not matter everything is possible if only few can figure it out. Area will develop and for personal pages I think future is bright with "mod-tools".

May be you get more competition for cheap solutions to smaller businesses but should not be difficult to argue why it is worth paying up to those with money to spend. What you use is established and well supported.  Compare with Themeforest http://themeforest.net/category/wordpress Not that many can do such pretty designs. Some themes might be bargains compared to hiring you as they are perfect out of the box, tons of features - more than you will ever need!, but what happens when it breaks with WP 3.1? or they want some weird mod/plugin? or they simply screw up in massive control panel? Many of these webdevs only have an email address as support. As you say if you get run over by Drupal it will be easy to find someone who can pick up Genesis. Low risk will appeal to serious businesses - more so if they become aware of danger ;) They will not just go oh well, we better find another 40$ then. I don't see much point for private users to use frameworks but understand your motives, think I would do the same. There is always a risk of things breaking and if business are actively using site, like 24/7 problems are not accepted for long. 

Yes of course. But these are Wordpress frameworks, like those mahesh2k have mentioned. Example StudioPress http://www.studiopress.com/themes/genesis

The transporter plugin, made by framework people, is to migrate SEO data between supported WP plugins/themes. You need a tool to migrate! Which points to the problem I mentioned. mahesh2k find it hard to see there is a problem because as long as you use a framework you can switch to something else just like that. Yeees, but within that framework :)

Because there is so big difference on how to implement? A select few know how, rest do not? I don't think so but recognize the idea of promoting stuff - from this very thread ;) There are many many options in WP world which is good. But these rather expensive frameworks have nothing to do with the typical user or the typical theme you see on WP site claiming to be "SEO Ready" or even the typical payware theme. They can set up own rules as they please. Kind of the idea with a framework. Selecting right stuff for the task is the big trick with WP so useful to be aware of this hidden and potentially very annoying problem.

There are tools for this like SEO Data Transporter (Genesis dude is co-author with StudioPress Framework) but is whatever you use supported?, migration tools always work perfectly? Today?, in 1 year?

Naturally there are some interest (and big egos) at stake, those who sell pricy frameworks might not be so friendly to annoying "3rd party" plugins. Those who make plugins might not love the fact better themes have main features build in already! Problem is still relevant. They seem to get along just fine though, after initial debate since this is also a business... Should Themes or Plugins do your SEO?
