TechWhirl (TECHWR-L) is a resource for technical writing and technical communications professionals of all experience levels and in all industries to share their experiences and acquire information.
For two decades, technical communicators have turned to TechWhirl to ask and answer questions about the always-changing world of technical communications, such as tools, skills, career paths, methodologies, and emerging industries. The TechWhirl Archives and magazine, created for, by and about technical writers, offer a wealth of knowledge to everyone with an interest in any aspect of technical communications.
I am a member of, and have found, the following STC SIGs to be very helpful.
I have gotten information from their newsletters, Web sites, and listservs:
Lone Writer
Usability
Information Design
I also am a new member of the Online Information SIG, but have not received
any information from that SIG. I understand, from the STC Web site, that
they publish a newsletter.
