Due to the lack of entries so far I am amending the rules. It is no longer required that an entry be on the blog of the person who submitted it. Being on any blog that is aggregated by the conference Planet will do.
This is known as a “guest post“. All it requires is that you email the post content to a blogger who you trust and they post it crediting you as the author. Guest posts are fairly common among serious bloggers, a google search will surely give more information.
