Share Knowledge, Not Features(shareknowledgenotfeatures.com)
You have something new and amazing for developers to check out. Yes, you'd like them to use your service, so it's a little self-serving, but chances are they actually will be interested, too. Inspired, you begin to draft a new blog post. These are the hardest for me to write and probably the hardest of your posts for me to read. It's because I hold us both to a simple, but high, standard. Share knowledge, not features.
