Hi,
subject tells a lot about overall thing, and media is writing a lot about the acquisition too, so no need to expand on general topics too much. though, of course, Wikipedia runs on MySQL, and there is some relation to the story that way too, but this story also means I'll be employed by Sun.
I usually kept my professional work completely separately from the wikipedia work - that both gave me freedom, and allowed me to avoid any conflict of interest. Though I've seen quite a few "MySQL is Wikipedia's choice, cause they have infiltrated the organization with engineers", it is somewhat opposite - I went to work for MySQL AB because it could use the skills I grew at Wikipedia in many quite interesting ways.
Sun, though, is a big company, which has hardware, operating systems, application servers, etc in their portfolio. Though people from tech team know that I enjoy rational technology solutions with irrational flavor of being open-source - conflicts of interest may seem probable in community and public opinion (as there already were mentions about mysql).
I'll continue to avoid being proxy of corporate interests, though of course, if there will be opportunity to progress open technologies both at my work and at wikitech, will voice the ideas and suggest solutions.
Oh, and that was one hell of wikivacation week :)
