I contribute mostly to articles on Microsoft or Microsoft products like Windows, and others on technology, Android, smartphones etc.
Notice: I used to contribute more actively to Wikipedia but lately edit less as I believe that while it is great, it is based on a flawed model of too much bureaucracy and guidelines, politics and wars between editors, non-accountability, insistence on citations rather than the truth, inaccuracies despite citations, bias, conflicts of interest, vandals, abuse, harassment and disrespect to its community. I *may* still contribute once in a while but only because my passion for technology, at times, exceeds my hatred and annoyances with Wikipedia. Sadly, the quality of some articles I once contributed to has degraded to shockingly bad levels so that's very discouraging. - xpclient Talk Edits
I tried to wait for a long time and see if the contributors who end up reducing the article quality would go away but they persist.
You can talk with me here. You can also e-mail me to take discussions out from Wikipedia.
See my contribs. Contribs from IPs 221.128.x.x, 202.149.x.x, 111.125.x.x and 183.87.x.x minus the vandals are me (for a certain period I only used my user ID for creating new articles or redirects so that vandals don't specifically target your contribs). Eventually, I started contributing using my username.
