Todo.txt++ is a hosted version of an open-source application built around the todo.txt protocol. Todo.txt++ has been online for a few months now, and has had many visitors. At the moment, we have 390 todo.txt lists in our cache.

We can perform some basic analysis on these todo.txt lists to see how people are using their todo.txt lists. This information can provide insight into which features are most popular with users which can guide what features we work to get into Todo.txt++.

Below are histograms of various features of the Todo.txt protocol or add-ons that show how many people are using each.

It looks like contexts and projects are commonly used.

We can now look to see how many tasks have been given a priority:

or the percent that start with a creation date.

Some users use the DUE: syntax to show when a task is due…

We can do some analysis on TODOs that are or are not done, but since we don’t yet support done.txt, we’re obviously going to be missing many people’s dones.

There are quite a few lists with little-to-no completed tasks. Specifically, 58.46 % of lists have zero completed tasks; presumably they’re using a done.txt file. If we exclude those, the graph looks a bit different:

It’s a bit more reasonable of a distribution.
