WordPress unnecessarily complicates this, so I’m simplifying it for you.
Click here to subscribe to my feed. That means you can choose to either 1. Get an email every time i add a new post, or 2. Have my new posts come up in an app like Google Reader or something similar. Joining my feed makes it easier for me to track my page views and gives my posts better chances of coming up in search engines.
If you’re a WordPress user, you can log into your account and you’ll see a link in the top left corner that says “follow.” Just click that and my posts will come up on your homepage. There will also be a link to my blog on the side of your page, which could get me more readers, so even if you’re already following my feed I’d love for you to also do this.
