The good:

This is one of my favorite sites. Its designed very pretty, but not only that, the search engine is amazing. The search bar on the left is so detailed, you'll definitely find what you wanted. It also has different filters such as popularity and the date entered. Users subscribe their art work.
http://www.newgrounds.com/
This is one of the coolest you'll ever visit. You can't go wrong, click anything and you'll come upon something awesome. Newgrounds is the leading website in flash animation and gaming. Users also subscribe their work. Click Flash Portal, and it lets you view the latest submissions, best of the week, and best of all time. Upon clicking a video, you can see the rating and comments before you view the video. On the left, you can find other work by the same user. It's also cool looking... lol
The bad:
http://spikedhumor.com/
Yes I know, this site is nice looking, but I still have a major problem with it. Although I love this website (it has the best and funniest videos), it has a terrible search engine and lack of filters, which makes it nearly impossible to find older videos. If you watched an enjoyable video you wish to show to a friend your only hopes of finding it is to go through each linear page going back by date.

Another site that I love, but I feel like its way too busy. If you have not yet guesses, I am an anime nerd (and PROUD of it). It used to be a lot more simple. The homepage would have an alphabet style search, making it easy to search titles. It took me a while to find it; http://www.animenewsnetwork.com/encyclopedia/anime.php

I know this is an angelfire page, so a fan must have done this, but all the text is CENTERED OMG! Fine, I got past that, but then searching the characters profiles I find the text centered again /sigh, and the picture is all the way to the left.
