I've been playing around with Footnote.com and am especially impressed with the connecting and networking capabilities this site offers.
One of the neat things you can do at Footnote.com is to connect documents with other documents on Footnote.com, either documents you have uploaded or records already on the site.
I found Elam Blain's pension records from the American Revolution when he was living in Ohio. After some searching, I found him on a muster roll in New Jersey, the state from which he served. I can link one document from the pension file to the muster roll. There does not appear to be one way to link his whole pension to the muster, but if another genealogist comes across page 56 from Elam's pension, they will see that document has been connected to another document. And if someone locates that page in the muster roll, they will see it has been linked to the pension file. Really neat. Imagine when more connections have been made.
I've posted a screen dump in this blog entry of the connection as shown (above) on my profile page at Footnote.com. Footnote.com members with a paid subscription can see the images using their account. Others will get a sign-in screen. 
Footnote.com members who come across the muster roll for Elam will note that someone has made a connection with that page. This can be seen in the image of the roll, where to the right of the word "connect" you will notice the number 1, indicating one connection has been made. Neat.
