I'm seriously thinking of ditching my Linkedin account. I know someone last week who was victim of a spear-phishing attack based on information on his Linkedin profile.

@andrew The most I get via my LinkedIn account are inquiries from recruiters inviting me to apply for Web site/application accessibility remediation work in industry. My profile emphasizes my qualifications - Arts degree, Law degree, Ph.D. - my social justice-related interests, and my involvement in Web accessibility-related standards development and research. It should be obvious that I'm not seeking to help remediate anybody's Web site, and that I'm looking for opportunities appropriate to those qualifications and interests, but apparently it isn't obvious, so I write replies pointing this out.
