Today I made a tag cloud of words form titles and descriptions of GDC 2011.
To do it, I Entered the GDC website, session list, clicked on "export complete list" button and exported list to CSV file format. Next I imported the CSV file in OpenOffice Calc spreadsheet, deleted all columns except name (for the first cloud) or name and overview (for the second cloud). Then I exported this data to a CSV file again, opened in in a text editor, made all text lower-case and deleted some common words like CANCELLED using Find & Replace. Finally I pasted this text to Wordle script to create tag clouds and tweaked some parameters.
