DISQUS

Very nice list. Montastic is simple and fast, the live RSS feed is very useful. Host-tracker is slow and bloated.

I find most of their placements are misleading and a very low quality. Many of these placements are not the publishers but rather a bunch of third party ad servers, proxies between the real publishers and Google.

That's only the invalid clicks they caught. From our experience, it's much higher and Google's customer service staff fight hard to deny any compensations or responsibilities.

This is another tool I created for Flickr.

Photo Watermark
If your photos have been stolen, displayed on some website claiming that they own the photo, or you worry about photo theft, I created a little program that can automatically add a line of text (your copyright notice, credit, date, whatever you like) into your photo. You can preview the watermarked photo and download to your computer, upload as a new photo into your photostream, or replace the existing photo on Flickr with this updated version.

I tried Jing and really like its interfaces. But it has an uncertain future/pricing

I would love if you can include some photos with the list. If it's because of copyrights, then it's too bad.

We use the promotional coupon to try LookSmart but have found it quite ineffective when comparing to other PPC engines, especially Google's AdWords.

Tried to pay for Ask.com but they kept saying they have problem processing the card!

Yes, I'm seeing those lawsuits coming for them too, but they really ignited the video serving market.

Great trick! Most of the extension just set maxVersion to be 1.0.x and therefore not compatible with 1.5

But does it look ugly though? (at least to me it does)
