Johnson has maintained a personal website about her work and experiences as an author since 2005, with blog entries dating as far back as August of that year. In June 2008, she joined then new micro-blogging platform Twitter as one of its early users, where she has likened her many posts about everything from the news of the day to searching the town of Guildford for a baking pan to the habit she had developed of leaving post-it notes around for others to read while working in theater productions. Book banning In June 2007, the parent of a student in Bartlesville, Oklahoma, challenged The Bermudez Triangle's presence within the school. The parent went on record saying "I didn’t appreciate that it was there", referring to the book being in the library. "I just don’t think homosexual materials belong in our schools." While book challenges in the U.S. are not uncommon, Johnson's response upon learning of the issue was to quickly publish a blog post on her website calling for greater transparency in the school system's challenge process. In an attempt to resolve the controversy, the school board did not remove the book but instead placed it in a restricted area of the high school's library. In an interview in January 2008 in retrospect of the situation, Johnson expressed the primary concern that censorship of stories on the basis of a character's identity will adversely effect all children, particularly those who happen to share that given identity. On the school's copy of The Bermudez Triangle ultimately being placed in a restricted area, Johnson stated: "To do so is basically saying to the gay kids, 'There’s something dirty about you.' Anyone who would say that is the true filthmonger." YA for Obama In September 2008, shortly before the general election, Johnson launched the inclusive political social networking community YA for Obama to support then U.S. Senator Barack Obama's candidacy for President. Intended as a way to help organize support and interest for Obama's campaign among young people and provide safe avenues for them to engage the American political process, YA for Obama used the online community publishing platform Ning, and comprised discussion forums, user-generated content such as videos and photos, and daily blog updates written by popular Young Adult fiction authors. Notable contributors included Judy Blume, Scott Westerfeld, Lauren Myracle, Cecily von Ziegesar, and Megan McCafferty. ShelterBox In February 2011, in response
