Started on October 15th 2007, the Agile and Lean Software Development Group on LinkedIn has now over 30,000 members. Looking at its growth over the years:

On an average, 350 new members are joining the group every week (a 7% growth.)

On an average, 13 discussions every week, but close to 300 comments each week is awesome. Shows that the group is very active. We also get a ton of promotions and jobs.

London, UK and San Francisco Bay Area seems to contributed highest number of members. Also pleasantly surprised to see Bangalore 5th on the list.

You can view all these detailed stats yourself at the group dashboard.

After uploading various videos from the Agile India 2012 conference, I was looking at some reports in YouTube. 2 Reports particularly caught my interest.

Demographics

India shows a large number of male viewers with a fairly average distribution across between age groups. While UK has a very large number of female viewers all in the 45-54 years age bracket.

(For some reasons, no demographics info are displayed for US.)

Audience retention

This reinforces my thinking that very few people watch conference videos online for more than 5 mins. (However they will enjoy the same talk if it was in-person.)

Would be interesting to find a way to distill any talk to under 5 mins.
