I've only just signed up as a Mega Supporter and played around with Alfred 2 Workflows for the first time this evening. My first attempt was a simple OmniFocus workflow, just to get a task into the Inbox, as I can never remember the hot key combination that I defined for the OmniFocus quick entry box. (I posted it online here but it's very basic and nothing most Alfred users couldn't figure out for themselves).
Getting Alfred 2 and the forthcoming OmniFocus 2 working together seems like a really promising opportunity. Looking forward to seeing what additional AppleScript support is in OF2.
