Day two of Cloud Expo Europe saw a surge in the volume of tweets about the event, up by 44 per cent from the day before. This was thanks in part to Derek du Preez of Computing’s article about a presentation given by the senior technology manager for Channel 5. This article alone accounted for 43 per cent of all 231 tweets about Cloud Expo Europe yesterday.

Engagement by exhibitors seemed to remain mostly flat, with just two additional exhibitors joining the conversation. That said, two exhibitors that were tweeting on the first day of the conference didn’t continue to engage on the second. This may be because they were tweeting about a presentation that they were giving on the first day to encourage people to attend it, and so on the second day didn’t see much benefit from tweeting about the event.

To me this seems like a bit of a mistake. Exhibitors that gave presentations on day one could have blogged about their presentation or posted the slides online. Equally, exhibitors that were giving presentations on day two, could have tweeted about the forthcoming presentation on day one, and talked about what would be covered, as Ivo Murris did on Wednesday when he posted a sneak peak of his presentation.

I also noticed a number of people checking in on Foursquare at the event, with Carenza’s CTO (@reidjc) bagging the title as mayor. However none of the exhibitors seemed to be encouraging people to check in at their stand. With many tech savvy people at the event, it seems a shame that companies didn’t encourage this activity and offer incentives to people that checked in at their stand. Perhaps next year, when location-based social networks may be more mainstream, we’ll see more companies looking to connect with people in this way.

In a search of news coverage about the 33 exhibitors I could only find 17 articles, which suggests that most companies didn’t make announcements at the event. This is a trend we’ve been seeing for a few years now with many firms gaining coverage around events by securing briefings or bylined articles.
