I used Zotero while going through University and it seemed revolutionary at the time. There wasn't really anything else that could properly import the citation info from journals, web sites, etc so easily. Most of them you would have to type everything in manually. Zotero changed all of that and truly made it easy. Glad to see that it has kept getting better and better.
