I have been using north for a few months (for seo and online marketing clients) At its heart it's a simple idea, instead of having to email your clients, post an update on the project on north and they receive an email update, along with being able to login if they wish and see all previous updates, commenting, liking etc..... They have been releasing updates and enhancements all the time and plan to continue doing so.
If you need an easy way to update clients on projects, whilst keeping that workflow in one place, then this is a great product for you.
