Considering health activism through blogging? Be careful what you wish for. Are you prepared to become a lightning rod for your cause? We’d all like to be happy little bloggers. You will face opposition, criticism, insults, and more. A lot of it will get very personal. The people who appreciate you the most are the least likely to let you know you’re doing a good job. Most days you will wonder if anyone ever visits your blog or reads beyond the headline on Twitter.
