Sermo had decent setup and functionality in the past but the site was sold and it’s really a horrible experience today. The app didn’t work well before and if they improved it lately the terrible content makes it useless.
Sermo used to be a pretty interesting forum for physicians, like SDN. They sold out about 4 years ago and started pushing pharma company surveys and mining physician posts for data to marketing firms. Its a ghost of what it was, and could have been.
