+LinkPeek.com, webpage to image, was a by-product

+
+**tldr;** When faced with pivoting or killing a project, take a good
+look at all possible by-products. Don't miss the hidden gem in a
+project's slag!
+
+Last year I built yoursitemakesmebarf.com, a novelty web application
+which allowed anonymous link submission. The software would
+automatically take
+`screenshots <http://russell.ballestrini.net/linkpeek-com-web-address-thumbnail-api-alpha-release/>`__
+of submitted links and curate a blog. I enjoyed building the site and
+the project served as my first Pyramid application.
+
+The project's original intent was to jokingly poke fun at ugly design.
+The idea never caught on. Instead the application angered website owners
+and attracted undesirable people. Eventually, I decided to take it down
+and come up with less combative idea.
+
+After witnessing the Goog release of "instant previews", I knew there
+was a market for a fast and reliable web screen shot service.
+
+.. linkpeek:: 
+   uri = https://linkpeek.com
+   size = 500x240
+   action = link_image
+   title = web page screen shot service
+   style = float: left; border-radius: 15px; margin-right: 15px;
+
+So I decided to bring instant previews to anyone who needed them. I
+wanted to build a fast, flexible, and easy to use screenshot API. After
+a few months I had a working prototype. I named the product LinkPeek
+because it described what the service was, and the domain was available.
+
+Next I built a website thumbnail generator to show off the software. The
+generator application helped reinforce the simplicity of the underlying
+LinkPeek API. It didn't require any downloading, installation, or
+waiting.
+
+About a week later on a whim I posted the generator to hacker news.
+I gave an honest title: 
+
+[linkpeek-hover uri="http://linkpeek.com/website-thumbnail-generator" text="Convert Any Webpage to an Image"]
+and within about about 30 minutes LinkPeek.com was placed on the front page in the number 1 spot.
+
+**Remember, when faced with pivoting or killing a project, take a good
+look at all possible by-products. Don't miss the hidden gem in a
+project's slag!**
