Sources for Web tools, utilities, and applications

[David L. Rodgers]

Besides Web4Lib, what electronic/print sources 
(e.g., discussion groups, publications, websites) 
do you and/or your webmasters regularly 
use/consult/recommend to identify/track available 
open source, freeware, shareware, or commercially 
supported web tools, utilities and applications (e.g., 
autoresponders, logging, domain alert, scripts) ? 
 
Thanks in advance for the help.
