BashTheBug on the Zooniverse News

End of week 1

BashTheBug went live on the Zooniverse website a bit over a week ago, just after midnight on Friday 7 April. Since then 1,134 people have participated, which is an average of 162 people trying BashTheBug for the first time everyday — see below.

Number of new users trying BashTheBug by day

I am impressed that there isn’t much of a drop in new users trying the project yet. The important context for this is that the existence of BashTheBug hasn’t been emailed to the Zooniverse user base yet; people will have only found it either by seeing it on the project list, or via Twitter.

Between them, these people have made a total of 45,375 classifications. When added to classifications that the beta-testers made, that makes a grand total of 80,103 classifications, which is awesome

Classifications made per day

That the number of classifications made per day isn’t varying as much as the number of new users suggests that people are coming back to the project and doing classifications on successive days. So who has done the most classifications? This is hard to plot, since if you try and plot a simple distribution of users based on how many classifications they’ve done you get something that looks like this:

Simple user distribution

As you’d expect, most people have done less than 100 classifications (I’ve only done about 150 and I’ve been showing it to lots of people over the last month or so). But, check out those little blips on the x-axis at high classification numbers: those are people who’ve done a lot of classifications since the project went live. So, let’s first order the users by the number of classifications they’ve done in descending order and then plot the cumulative fraction of the total classifications that number of users have done. This looks like this:

Cumulative user distribution

This shows that the top 10 users did 14% of the classifications between them; that is a staggering 648 classifications each. In fact the top two users have done 1,746 and 1,758 classifications, which is over ten times what I have managed. Well done and thank you!
