Okay...so I think I had WAY too much fun with the musicplasma.com database! I was enjoying doing the movie search. Do I think I would ever use this for practical reasons or in my classroom?? Probably not. But still very fun to play around with. It is a very visual search engine that makes a giant image web relating movies to each other!
As for other search engines, I did some side-by-side comparisons of the results from a few different search engines. I am sort of stuck on Google when it comes to day-to-day pop culture searches. However, nothing beats the databases for academic material!
