Part of what I'm trying to do with HelpSpot is change the game for help desk software using RSS. Seth Godin has a nice post about how RSS/Blogs are changing communication and applications. He points out Basecamp which lets you manage your projects with RSS goodness.

On a side note, it's interesting to take a look at technically how he linked to Basecamp. He did it in a very search engine optimization friendly way. Rather than link to "Basecamp", he instead used "Project management and task management software: Basecamp". This is much much better from an SEO perspective for the Basecamp site. Wonder why he did that?
