Great post. I hadn't heard of or used HelloSign. I can definitely use this right away at work. I have to sign PDF quotes regularly and this would save me a good amount of time. I currently have to print it out, sign it, scan it back in and then attach and send to the vendors. You just gave me at least 15 min back in my day. Thanks!
Have you ever heard of IFTTT.com? I've started using them lately to help increase my productivity. I heard about them at CES this year. It basically allows you to automate tasks by creating recipes. Its pretty cool because there is a big repository of already created recipes and a pretty good social sharing system on the site so even though its brand new there are a bunch of recipes. Highly suggest you check it out.
