Where do you draw the line on social media?

I try to keep up. I have a feed reader . I blog . I comment on other people's blogs. I tweet . I have multiple websites . I have accounts on Facebook, MySpace, LinkedIn and others. But you have to draw the line somewhere. I wrote earlier about being app'd out . I still feel that way. But each day I feel farther behind. Maybe not behind, but not necessarily maximizing potential. I don't Digg. I don't StumbleUpon. OK, maybe I do like once a month if I have some spare time. But I know I am missing out on a lot of cool things. I usually check out other people's links to cool tools or the next new thing. But right now, I feel like I am in the Dip . Any suggestions on how to get out?

Since I led a session, that meant I only got to go to 3 true sessions. Sorry, I don't count Joy Behar and the closing session. Although Marshall Goldsmith was good, I probably wouldn't have gone to see that speech as a Learning Lab. 3. Based on #...

Sunk Costs, Marginal Costs and Economics

When I was in college, I hated Economics. Then, several years later, I found myself teaching undergrad Econ and learned an appreciation for it. Now today, I have an even bigger appreciation for it. I have also noticed that not enough people have a solid grasp of some basic econ concepts that can be applied to everyday life. Two of these are cost related. Here are some basic definitions from The Economist website : Sunk Costs - When what is done cannot be undone. Sunk costs are costs that have been incurred and cannot be reversed, for example, spending on ADVERTISING or researching a product idea. They can be a barrier to entry. If potential entrants would have to incur similar costs, which would not be recoverable if the entry failed, they may be scared off. Marginal Costs - The difference made by one extra unit of something. Marginal revenue is the extra revenue earned by selling one more unit of something. The marginal cost (or whatever) can be very different from the AVERAGE c...
