Here’s a quick look at some of the posts that caught my eye over the past week…

JLP talks about how to buy an exchange traded fund (ETF).

FMF talks about whether parents or kids should pay for college. It’s an interesting question, and there were a lot of interesting responses.

Jim wonders about how to calculate net worth for couples. In our case, my wife and I have done everything jointly since the very beginning, and it’s worked out quite well. Jim also broke the 500k mark in terms of visitors to his site, and guess what? I was within two seconds of being the half-millionth visitor, but I ended up as #500,001.

Flexo pointed out an article that argues that having multiple interests improves your brain function.

MBH is looking for opinions on car DVD players. In our case, we have a 9 inch TV/DVD combo (CRT, not LCD) that we harness between the seats in our minivan for long trips. Sometimes we even plug in GameCube, and we might just do the same thing with a Nintendo Wii if/when we buy one.

Nick is bummed out by his short-lived compact fluorescent lightbulbs, and I feel his pain. I switched over our entire house to compact fluorescent lightbulbs this past summer, and we’ve already had one burn out. Grrrr…
