Thanks to Thumbshots.com provide us the thumbnails service for website.

Thumbshots.com is basically a service for taking snap- shot photo of the website you input.

Advantage of using  thumbnails in bookmarks allow people recongize the websites link they added in the Bookmarks.
Sometimes, it is hard to remember when you have so many link in your bookmarks, by looking only at the link title and
description, it's not good way to tell us "Is this the website I want to go?". 
Because, human are not memorize good when text are only source.

This is an example of mind, the figure below is my recently bookmarks list.

As you can see, I am interested in websites about web desgin, and graphical icons.
So all the similar types of websites are labeled nicely, and named prefect.

But if I have no thumbnail, I would not recongize all of them, since their title and description is similar.
(All the links is about icon, CSS, web template, web design.)

Therefore, you are enable to recongize your previous experience in those websites, by the thumbnails image.

Hope you guys like it, it's not any special fancy feature, but thumbnails is helpful as a tools.

So, that's why we decide to added on Muecs Bookmarks and Mashups Share
