We built Extendy to fix a couple pain points:

• Websites typically have links to ‘subscribe to RSS’, ‘follow us on Twitter’, ‘share this webpage via Facebook, digg, ...’, site search functionality, etc. But these things all exist in different spots on every website. We’ve tried to create an easy dashboard for visitors to quickly find those features of your website.
• By having your latest tweets and blog posts easily visible to your users, we hope they’ll keep surfing around your website more.
