Gmail has been another wonderful product. Although I started using it in 2005, it was this year that I really started to appreciate its features, ease of use, open standards and fantastic spam filter. The account size is more than generous, the ads are not intrusive, I love being able to label my messages, and the search feature is right on. On top of that, I can retrieve copies of my messages through the POP protocol (that's Pop, as in my last name...), and make them searchable on my iMac through Spotlight.
Finally, I'm grateful for Loudblog. It's an open-source podcasting platform that's fast, easy to install, and easy to use. I use it to publish my three podcasts: ComeAcross and Dignoscentia (in English and Romanian). I have to apologize because I haven't had time to publish any podcasts recently, but that doesn't mean I don't appreciate how easy Loudblog made the publishing of podcasts for me.
So there you have it, four products that have made it incredibly easier for me to publish content and communicate this year. I'm truly thankful for them, and who knows, maybe they'll help you as well!
