The Stats Project aims to provide a logical reference point for all OpenOffice statistics, including downloads, mail list, website, and issue tracker activity. Everyone is welcome to join. We in particular need people who can help create appealing and intelligible charts for public consumption.
We use the marketing@openoffice.apache.org mail list for work discussions.
Another source of statistics are those generated by Ohloh:
These numbers should be taken with a grain of salt, and one should be cautious when comparing numbers across projects. Contributor numbers are especially sensitive to development methodology and tooling, e.g., a project that uses distributed version control will see a different count than one that processes patches through a smaller core group of developers. Projects also differ in what project resources they include in version control (Ohloh looks at files under version control), and which version controlled files they associate with their Ohloh account. For Apache OpenOffice our Ohloh account looks at files associated with our two main project deliverables: the OpenOffice source code and the website. For historical comparisons the Ohloh account also looks at the legacy OpenOffice.org repository for commits prior to June 2011. The safest comparison is to look at the trend for a single project over a period of time when version control and commit process is constant, e.g., since June 2011 for our project.
