General

• FreePDFConvert.com - this site does a good job of converting PDFs to Word format.  You can get the converted document sent to you via e-mail.

Web

• 11heavens.com - Montreal-based web developer specializing in Drupal; hers seems to be a widely read site, and she has tutorials on ActionScript, JavaScript, Drupal, and more
• Codebix.com - site that presents a nice aggregation of Web-related articles.  It seems to be more focused on Microsoft technologies - ASP.NET, Silverlight, Visual Studio, etc.
• 14 Best CSS Editors for Web Designers & Developers - 14 great tools just for CSS.
• Slickplan.com - web-based sitemap/flowchart generator that allows for the creation of free sitemap and flowchart design (from their website).
• OpenDNS - Google has entered the DNS space with its own offering, extending its grasp around the web even further.  I switched recently to OpenDNS's free service, mainly to try something other than what Comcast offers.  The best feature is probably the statistics it gives you on sites you visit.

Other

• Zvents.com - a good way to find out what's happening around your town.  I've used it several times and it generally has a good number of listings.
