I use and recommend all of the following Web tools and sites ...
Amazon
Time is money so why trail around at real world stores? I use Amazon to find it, buy it, and ship it, in seconds.
Cision
For their int'l press contacts database, so I can follow up with press when we post summaries of their articles on OPW and SNW.
Conduit
Custom toolbar I offer to my readers to help keep them connected with the news.
Feedblitz
Allows my readers to get new blog posts in their email every day.
Feedburner
My preferred RSS feed. Some good publicity tools also.
Flock
A leg up on Firefox. My new preferred browser. Great RSS reader.
Google Reader
Simple, foolproof web-borne RSS reader.
Plaxo
I use this service for ecards and birthday reminders more than anything else.
Sidestep
Most time efficient site for finding best-fit, best-priced flights, hotels and rental cars.
SpamArrest
No more spam. Nada, zero, killed it all.
Typepad
Fairly simple, reliable blogging engine. Word Press is my #2 choice.
WebMasterWorld
For getting the skinny on SEO and online marketing.
I'll add lists under categories for Fun and Hardware that I use each Thursday for the next 2 weeks. Finance, Management, Telephony and Web have been covered so far. Click on the 'Tips' category (see category cloud to the right) for future reference.
Please leave a comment if you have any additional web productivity tools that you can recommend from personal experience.
