… and its ties to OpenSource

• 2004: Andreas Gohr gets task to install wiki for company intranet documentation
• none of researched wikis fulfill all requirements
• he built the core during one weekend

• open-sourced nearly right from the beginning
• others see need to improve and collaborate
• revision control essential

• 2005: syntax plugins easy to make
• 2005: templates change look and feel
• 2005+: more types of plugins
• 2010: code moved to GitHub (“social coding”)
• 2012: jQuery added

• general multilingual support
• OpenSource is efficient (if successful)
  • many improve one product
  • can be adjusted to specific needs any time
  • easier to find support
• costs for open and closed software often not that different (main cost: support)
• freedom to code what and when you want is very motivating and often produces better quality
• includes freedom to say No, but easier to pay someone
