There have been lots of new toys to play with lately, with Twitter launching their new "follow" button and Google launching the +1 Button.
You can get them here and here:

And you might be able see them in action right here at this blog post, somewhere to the right of my smiling photograph (although the +1 button seems a bit unreliable at the moment).
Your "friends and contacts" will see what you have favourited with the +1 button, according to Google. This seems to mean people who have connected to your Google profile. I'm a bit hazy because I personally have never used my Google profile for anything, nor connected to anyone else's Google profile, so I'm not sure how it works. I use Facebook, Twitter and LinkedIn, as well as Skype and Windows Live, but that's it.
Having said that, Google also suggests that the number of +1 "votes" received by a page could appear next to its entry on Google search pages. Google explains:
Well, if that's going to work as it sounds, doesn't it change the very nature of Google search from an engine driven by complicated algorithms to one driven by user recommendations? Or am I going too far?
The new Twitter button seems very nice though.
