At Cloudforce a few weeks back I was asked to participate on a panel which discussed our favorite AppExchange apps. I commented that my favorites were all from Force.com Labs, because they were open source, free, and an easy way for Red Argyle customers to try out some new things.
Upon my return, I was asked to write a blog about it, that would be posting to the AppExchange newsletter. You can read the finished article here.
In the post, I outline my favorite applications with some links and screenshots so you can consider them for your Salesforce instance today!
