I know linkedin helped me a bit when I was freelancing. But even now that I am taking a break, I guess there are a lot of uses for Linkedin. I started using it more because I use Digsy at work and it connects with Twitter, Facebook and LinkedIn. But I barely even tapped the surface. I know that a few posts about Magento and Wordpress got me a few jobs.
Great little tool. I downloaded an old version back in the day before it was more user friendly. It has come a long way. I have another icon on my taskbar now. A great tool for finding just the right word that just won't pop into your head
While your average online customer may not want to manually type skus and quantities. But if some of your customers buy in bulk, they may find forms like these convenient. Buyers and purchasing agents are used to using tab and enter to fill out spreadsheets. They can blaze through a form like this 10 times faster than pecking around on your site, adding products one by one to their shopping cart.
