So especially around the forums, I see talk about easy screen shot sharing applications for PC. I know @Aryanix was just looking for one. I video came up in my RRS today and I thought I would share, along with a few other pieces of software as honorable mentions.
Personally, I use CloudApp. They are by far the best. Although, you have to be ready to pay a premium price. It's $99 a year. But, they have a free version as well if you want to try it out first.
They have a more expensive plan, but it's meant for real power users and/or teams. The reason I love CloudApp is because of it's multi-platform support as well as awesome support/dev team that drives this app. There are plenty of third party apps for iOS and android as well so you're not stuck with the app this company put out. Personally, I love ClouDrop because it's quick and has a pretty interface. I use this software all day, every day and I don't know what I'd do without it.
The app that I came across today is Puush. You can learn all about it here. While watching that video, I scrolled through the comments to see what other software people were using, and obviously GAYzo...whoops, i mean Gyazo - which I personally am not a fan of but I know a few people here use it. On the bright side, they did jsut add GIF/Video capture support which is cool, so I'm going to try that out today and see how well it works. My personal gripe with Gyazo is that as soon as you upload, it opens up a new window with the content. Personally, I'd rather it just copy the link to my clipboard and I can use it when I'm ready. But that's just me.
In addition to these two, another free option is Lightshot. I have not tried it out yet, but from the comments on that Puush video, it seems to be what everyone is using if they aren't using these options.
So there you have it. If you're looking for a screenshot app and gives you the ability to quickly share screenshots, pictures, videos, etc. etc. - these are some great options.
Your other option is literally creating your own software like Paronity did...hahah.
Edit: Anther honorable mention from @Wags! Thanks buddy!
MHO Greenshot is one of, if not the best screen shot software out there. Allows annotations to be added to your screenshot, plus a plethora of other features. Best of all, it's FREE! http://getgreenshot.org/
