I recently read a great blog post by John Jantsch on his Duct Tape Marketing blog. I subscribe to more than my fair share of blogs via Google Reader. If you don't have Google Reader, I highly recommend you consider it for organizing your RSS feeds. I love that I can read my feeds on my phone now. But I digress....
What do you do after you post blog content?
1) Nothing. I sit back and wait
2) Post it to all my social networks at the same time
3) Implement a sharing strategy based on what I know about my audience
Now you know the right answer here but take a moment to read Mr Jantsch strategy. It's a great mix of Facebook, Google+, LinkedIn, Twitter, StumbleUpon, and Delicious. And be sure to read the comments, too.
