2009 has really been the year of Twitter. Everybody has been sharing their every move with the world (including me) which has given us a greater insight in to the lives of celebrities and designers. Vogue Italia have taken their Twitter obsession to a new level by dedicating the cover of the December issue to it.

Steven Meisel has made a collage of TwitPics starring top models which is sure to provoke mixed reactions. Gisele Bündchen, Lara Stone, Natalia Vodianova, and Christy Turlington all feature in the collage. What do you think of this cover – is it taking Twitter a step too far, or is it a clever way to acknowledge a big trend?
