Yeah i see how this will play out. Now we have 2-3 Buttons per item just for facebook. Because you can read something and like it aswell as want/watch it.

More buttons higher pageloads because not many sites use the 2-click versions yet.

Maybe someone should rethink the overall share model and find a new way to do it. Over time there will be more and more buttons all over the place.

Do you mean there's a two-click version of the Facebook Like button? Do you have a link to more information about it?

It`s actually only a technique where you replace the like button with a static img and on an mouseover event or first click you replace it with the original like button.

Its good for improving page loads because you dont have to wait for 3rd party servers and also its an improvment for user privacy because your site is not automatically sending content informations into the graphs of all these sites just because someone opens a webpage.

I can only link to one project i know of, but its in german only atm http://www.heise.de/extras/socialshareprivacy/ another example would be techcrunch but as far as i can tell they only use it to improve the overall pageload experience.

Unfortunately, I can see Digital Agencies and SEO Specialists recommending (and clients of both requesting) a slather of buttons for every conceivable type of Like on the off chance that someone actually clicks one.

I don't mean to point fingers, but I don't think this sort of thing is going to get any better: http://i.imgur.com/VeUr1.png

The veritable array of social buttons that appears on numerous Web sites tends to be one button per social network. The idea is not to try and ensure that people click at least one button, but rather to ensure that they almost always have one that they can click. I don't see how adding all of "Like," "Read," "Want," and "Watched" to one's site would help solve that problem.
