Tablogging is weird. It's not really sharing links, but it kind of is. It's sharing a whole bunch of links at once. Not to share the links exactly, though you can visit the links if you want. I guess it's trying to capture what you're doing on the internet, really quickly. I wanted to share what I was looking at, but sharing is hard, and you can't do it too much.
I built a Chrome extension that captures the titles and URLs of all your open tabs, and then sends the information to another page (say, my tablog) to display all of your tablogs. So, with one click, I can share what I'm up to.
I bet that cleared nothing up.
