Like last year, I collected all tweets posted to #xbio and #eb2014 over the Experimental Biology conference. Here they are in a CSV file. Last year there were 5,455 over a 10 day period, and this year there are 6,223 over an 18 day period. During the last 8 days there were only about 120 tweets, so there were about 600 more tweets this year, and that was with a technology fail and loss of about 20 hours of tweets on the 30th (see graph). So there were probably at least several hundred more in that period. Also like last year, I captured photos posted to the hashtag and uploaded them to this tumblr so they are all in one place. Below are some additional comparisons*:
Tweet Frequency Over the Conference
This year reached a higher peak tweet frequency compared to last year:
Tweets Per Person and Number of Tweeters
There was a lower average number of tweets per person this year, but more people tweeted to the hashtags.
The median for both years was 1 tweet.

Here is a network graph showing the relationship of the most common words (several are twitter handles) in tweets and retweets that contained the hashtags. The connections between words are weighted by how common they appear together in tweets.
These are maps of the home locations of each person who tweeted to the hashtags and who included their home locations in their profile. It is a similar pattern to last year: Most are from the US, but some are all over the world (click to enlarge):
This year, the hashtag was switched to #xbio instead of of #eb2014 (last year was #eb2013). I looked to see if people adopted the new one. Most appeared to get the message:
- 83% of tweets contained only the #xbio hashtag
- 12% contained only the #eb2014 hashtag
- 5% contained both hashtags

*Tweets were collected using the Twitter Streaming API using a node.js app on Heroku. Locations were geocoded with Google Maps API using Python, analyses were done in R, and the network graph in Gephi.
