A little methodology
Generated statistics using:• Enron Email Corpus (252,000 messages)
– www.cs.cmu.edu/~enron/– http://www.isi.edu/~adibi/Enron/Enron.htm
• Random Twitter Corpus (490,000 tweets)– Twitter Streaming API (“Gardenhose”) – Collected since 11/5

Rich Content
87.6% of Email is 141 characters or more

Rich Conversation Structure
• 41.9% of emails are “multi-recipient”– More than one address in To/CC fields
• 5.6% of tweets are “multi-recipient”– 1/4 multi-RT– Otherwise, spam-heavy

Rich Controls

• Only 1.9% of email messages were publicly broadcast to a full site

Can an old communications metaphor learn new tricks?
• Web 2.0 Technology beats email with:– Lower barriers to entry– Publicly searchable data– Immediate public validation– Opt-in publishing

Lowering the Barrier
• 140 character limit is a psychological boon – we worry less about sending a message
• Email is moving toward shorter messages– The rise of mobile phones– Conditioned from using web 2.0 services

Searchable Expertise Data
• Publicly searchable data is very valuable
• “Interesting” is incredibly relative inside companies – what’s interesting is what relates to current projects

Will Email get a “Like” button?
• Twitter users who “stick” are often the ones who get early @replies and early retweets
• Feedback from email is often private
• How can we publicly acknowledge and encourage public sharing of useful material?

Opt-In Publishing
• Mailing list traffic “fills up their email with discussions they don't want to subscribe to” – Just last night
• Mailing lists will become more like activity streams

Summary
• Email has a major advantage in the complexity of the relationships and content it can express
• Web 2.0 technology promotes public sharing and creates valuable searchable data
• Email will still be here in 5 years, but it will look like a combination of email and Web 2.0
