To like or to share, that is the question!

y big question, can you have a combined facebook/bookmark and facebook/like icon? Are they distinct?   As I researched this question, I found this row of icons on a forum....

 Background.  Like many, I have littered my sites with little icons or widgets such as the following:
del.icio.us

But, my other sites have other icons related to bookmarking such as:
     


Another site has a single icon which has everything in like this:



Some others focus on RSS subscriptions:
 Subscribe in a reader


Or, we ask you to subscribe as either an email or RSS reader:

In addition to bookmarking and subscribing, you can friend (now like/facebook) or follow (twitter) or visit (facebook).

You can write your own code or, if you google "facebook twitter icons", you'll get oodles of sites that will provide you icons and generate your code for you.  I wonder if their code will on Facebook, both create a link and an icon.
Widgetbox will give you icons and generate the code.

Test Preparation - Advertising

Test preparation -would advertisements for preparing for tests be of higher value than advertisements for just generally building vocabulary skills?

At Vocabulary.co.il, we are engaged in a great google-adsense experiment. We're trying to find how we can adjust our page so that ads of more value per click appear.

We've been stuck in the $.09 basement for awhile with adsense touting vocabulary games, vocabulary activities, and free word games. By changing the title and building a few incoming links with words like test preparation or SAT preparation, will the ads change?

It seems to be that preparation for the standardized high stake tests merits maybe $.12 clicks which would be a 30% increase in revenue (which we would like :->)!
