I'm sure there is merit to running bazaar to filter through your library, but bazaar's real power lies in its ability to put cards into your graveyard while digging. Due to dredge being such a big deck though there is generally a large amount of graveyard hate running around making people avoid other graveyard based decks.
As for other decks recently that played bazaar I know there was the Minus Six deck that would transform from Worldgorger combo to a Time Vault deck. Here's a link for that deck

One was a madness list playing Basking Rootwalla, Life from the Loam and Circular Logic. The other was in some of the 3 decks 1 box builds by Vishnu Harris that had a re-animator package and accumulated knowledge in them.
I hope this helps and good luck on finding a way to use your bazaar's in a non traditional manner!
