I lurk on #openmoko generally. Currently involved in reinsulating my house, http://www.mauve.plus.com/walls/ so don't have much spare time. :( firstname.lastname@example.org will reach me.
Of pages that I've largely written, I will tend to harshly edit down comments that in my view do not fit the style or are better off in another article, then note that on the discussion page. If you have comments about me ripping your prose to shreds, or making something less clear, please note it on the discussion page, and if you feel strongly about it and I don't get back to you within a day or so, revert.
