I'm using Trello instead of post-it notes, no danger of them falling off the wall! All my tasks are arranged on boards from "Phase 1 - Getting Started" through to "Phase 5 -Pie in the Sky Ideas". I also have a board for blog post ideas, and I can add notes to each idea all ready for when I write that post. I've also used the coloured labels so I can see at a glance what sort of task it is, be it blog post, website, social media etc.
So Phase 1 is to setup the blog and to publish at least 3 posts by the beginning of April.
