Lin, yeah LOOK has been steadily going down, and apparently they have some major problems. However, my "feeling" is that because they are in the pay-per-click market, one of the big boys will not let them sink totally, either that or they will bottom out soon and make a nice rebound. My thinking is for .80/sh I can put some fun money on them. They are one of the last major search engines from the 90's that has not gone backrupt or been swallowed by a bigger fish. I wouldn't be suprised if they are bought out by yahoo or google in the near future.
INCX I like a lot, they have a great concept because they are actually a middle man that provides the pay-per-click service to search engines.
If you've ever tried to promote a website, you know that pay per click by keyword submission is a great product. Especially if you are a very small business. Collectively the tiny website businesses are far bigger than the popular websites. The market is already huge and growing.
