I love how easy it is to use! It's so simple that even my 10 year old can figure out her way around. We have been using this app since we started our blog about 8 months ago. The benefits are endless - you get more exposure than just one post alone would give you; plus your content gets ranked higher in search engines like Google which means more traffic; also when people click through they see who posted what (and therefore where their interests lie); great tool if you're serious about building an audience and not only blogging but having followers too. Nothing really at all as everything works fine. This has saved us hours upon time spent searching blogs looking for guest posts. And best part? There aren't any downsides either :) Highly recommended!!
