Nick Wilson, of Performancing, has a great article up that while the summer is basically half over, it may help you revive your already dying blog before it’s too late.
He gives some short, bulleted-list points that are very relevant like:
3. Hold competions, polls, and generally break out of the norm for a bit
5. Recruit guest authors from your core audience, and go to the beach for the day
6. Do reader spotlights, the Blog Heralds How I Blog series is a great example of this and the point above
