I think they are synonymous currently. I wouldn't mind seeing Cards used for "static" things and Widgets for more interactive... widgets.
In my opinion, you can interact with a widget. In this case, it is not a widget, since you can't actually follow or star.
May I offer a minor note? More correct English would be "Available for hire" rather than "Available for hiring".
These look great. Kudos!
Thanks, I've fixed that.
Ya, nice!
Nice, the design reminds me of the twitter 'cards' which embed tweets on blog posts and such. Which is great because it is already a familiar design paradigm and I'm used to it. Great work!
This is an awesome idea. Totally looks good and I'd definitly add something lile that on my portfolio. I hope this will get attention by the gh guys :)
