I agree. I see no need to waste bandwidth and page size with an external library to add an image curl. If I wanted that I would add it using my favorite image editing program. The JavaScript image processing libraries he mention also make the image grainy. I'm really not impressed. If there is one possibly "essential" javascript effect it would be the spinning ajax indicator or a progress indicator for uploads and other time intensive operations. None of the "effects" mentioned by the author are anywhere near "essential."
