A) If you click on any individual post on any Scienceblogs.com blog, you will see new sharing buttons on the bottom which make it very easy for you to, with a single click, send the link to that post to Twitter, Facebook and other social networking services (or e-mail to friends).
B) There is a new page on Scienceblogs.com – this one – where you can see all the comments made recently on all of our blogs. And, lo and behold, they are not all on Pharyngula posts! Once you scroll down and read them all, just refresh the page to see the new ones. Click and add your own comments. Get to know the bloggers (and their regular commenters) you are not familiar with yet. You can get to that page from any blog by looking at the right-hand margin and clicking on the “More Scienceblogs” menu, then choose “The Latest Comments”.
