Alfred Tips
I don’t normally link to weblogs, but I really like the way the Alfred team share in-depth tips and tricks here. For an already feature-rich app with a fast pace of development, it’s a great way for users to keep abreast of new features and learn the ins and outs of existing ones.
And, from a more cynical perspective, it’s superb marketing for the app, nudges users in the direction of the Powerpack paid upgrade, and no doubt makes it easier to write more formal documentation down the road.
TL;DR: Developers, please blog like crazy!
