This is a list of my main sources of income, and of any other work-related benefits, as of 1 October 2011. I will update this as and when any major changes occur.
My main sources of income are from writing for Computerworld UK, The H Open and Techdirt. In the past I have occasionally written for other titles, but not recently, and given my many commitments I think that is unlikely to change.
I also get paid to give talks, mostly on free software, intellectual monopolies and digital rights.
I occasionally accept paid-for trips to attend conferences related to my work; I aim to declare that fact in any writing that comes out of such visits. In the past (ten to twenty years ago) I accepted these routinely, as did all journalists. For the record, the company that invited me most frequently back then was probably Microsoft....
I am not, and never have been, a consultant for any company.
As for unpaid positions, I'm on the Open Knowledge Foundation Advisory Board, and also on the Advisory Committee of the Climate Code Foundation.
I do not own (and have never owned) any shares except those that might be hidden away in financial instruments I may have or have had: I have never tried to find out if there are any, or what they might be. Similarly, I do not have, and have never had, investments in any company.
I no longer accept freebies in the form of review software/hardware (though I did a couple of decades ago when this was standard practice.) I buy all my own computers and smartphones at full price (luckily, the software comes free...)
I very occasionally receive free review copies of books on areas I'm interested in, but I'm trying to discourage this since I never have time to write the reviews (er, sorry about that.)
