Get Busy Sharing, Or Get Busy Dyin'
So you've got page after page of amazing products/content, right? You probably also have a few of those widgets to help users share that content with their friends and colleagues, be it through email or across social networks. It is your responsibility (the Web professionals) to help users share information with others. The benefits are that your message, product, etc. gets additional reach into an audience that by all accounts is qualified as it comes from a trusted counterpart - their friends.
There are many services which facilitate this sharing - ShareThis being perhaps the most popular currently. Another which is making the rounds of the Web this week is Siphs - a Web-based service which enables its users to share and tag any and all Web pages at your site. It's perfect for template-driven websites such as WordPress but it can work with pretty much anything if you don't mind some tweaking.
Siphs works very well - I've tried a few similar services which always seem to be buggy at best. When a visitor clicks the Siphs "Share" link, they are directed to an intermediary page with different sharing options (email, social networks such as Digg, Facebook, Twitter, Stumbleupon, etc.). For the Feedburner folks in the house, there is also a FeedFlare - you can see it on action on the Website Magazine Feedburner XML page (just look for the 'Email this' link at the end of each post).
So what's all this sharing going to cost you? There is a free version of Siphs (which is what Website Magazine is using) that enables you to do some decent branding and receive some helpful reports. If you want to take it up a notch, the upgraded plans (between $100 and $200) are very reasonable for the functionality you'll get.
