Quoting Jesse Zbikowski (embeddedlinuxguy@gmail.com):
That's true, and interesting to note that he couldn't even be bothered to include this information in his posting. Personally I am non-plussed at how many recruiters don't bother to communicate where the job actually is. I don't know that there are any geographical restrictions for sf-lug job posts, but it would be good practice to include the city in the subject line or the first few lines of the body. Just my two cents.
FWIW, I've also managed SVLUG's Jobs mailing list for quite a few years, and one of its rules is that all postings for full-time positions must be for jobs within 75 miles of San Jose. One of the most frequent reasons listadmins rejecting postings to that mailing list is recruiters failing to include location at all. (Postings that refer readers to a URL for details get immediately rejected, because the listadmins need to vet postings from the Mailman interface, and so postings are expected to be self-contained.)
SVLUG's experience at the time (see qualifier below) was that it was impractical to permit jobs postings in the main Linux discussion mailing list under any rules whatsoever, because a large number of recruiters would always just ignore any rules and 'apologise in advance'. (I should stress that it's just _some_ recruiters. I really feel for the careful and diligent ones.)
The SVLUG listadmins eventually not only created a separated, dedicated Jobs list, but also discovered the hard way that it had to be fully moderated.
(Most of the badness occurred during the dot-com explosion of business, in fairness.)
