1) Have you ever collaborated or worked with another blogger to mutually grow or improve your blog?
I've done a guest post and am setting up a skype interview with a blogger in my niche.
2) How have you reached out to other bloggers in your niche? What has worked best for you to make connections with other bloggers?
Emailing seems to work well. Since starting 31dbbb I've built up a few connections (guesy posting), some out of my niche. It'll be intersting to see how the connections develop over time.
I've also recently spotted some brand new blogs in my niche so I'm going to fire off some emails to them today!
This is such hard work, but great for me and my blog!
