I'm happy to announce that we have four interesting and varied keynote speakers lined up for the BlogTalk 2008 [1] conference on social software in Cork this March.

• Nova Spivack [2] - Founder and CEO, Radar Networks [3]
  Nova is the entrepreneur behind the Twine [4] "knowledge networking" application, which allows users to share, organise, and find information with people they trust. He will talk about semantic social software for consumers.
• Rashmi Sinha [5] - Founder, Uzanto [6]
  Rashmi led the team that produced SlideShare [7], a popular presentation-sharing service that some have described as "YouTube for PowerPoint". She will talk about lessons learned from designing social software applications.
• Salim Ismail [8] - Head of Brickhouse, Yahoo! [9]
  Salim is a successful investor and entrepreneur, with expertise in a variety of early-stage startups and Web 2.0 companies including Confabb [10] and PubSub. He will talk about entrepreneurship and social media.
• Final speaker has been selected but has yet to be 100% confirmed.

You can see further details and longer biographies of the keynote speakers at 2008.blogtalk.net/invitedspeakers [11]. We will also have two invited panel sessions, the details of which will be announced shortly.
