PCWorld blogger Rick Broida, who has written about Eyejot before, tells you how to make free phone calls with GizmoCall, send video mail with Eyejot, and more in his article Cool Browser Tricks From Hassle-Free PC. He likes the fact that Eyejot is browser based and writes:

"Because there's nothing to install, you can use Eyejot on a whim.
Record a birthday greeting for a loved one, let the kids goof around
for grandma and grandpa, act like a dork for your blog (you can record
a profile video and embed it on your site, as I've done here), or
whatever."
