I'm a long time Quicksilver user, and a recent Alfred user. I miss Quicksilver's style of fuzzy matching which will match anything without typing spaces. For example if I'm using the iTunes browser and I want to select "LCD Soundsystem", typing "lcds" will not match in Alfred, but it will in Quicksilver.
It would be great if there was an option to get even fuzzier matching than "Full fuzzy match from word boundary".
