www.fragwagon.com is a TF2 dedicated gamer's blog. The site opened in April of 2008 and averages around 10 to 15 posts per month on anything from gameplay to random videos related to TF2. The posts are broken down into over 10 different categories, such as "Mapping", "Video", "Mailbag", and my favorite - "Seen on a cooler blog".
Overall, www.fragwagon.com is a decent blog that could be used to find useful information about TF2. It is nice to see a gaming blog that doesn't just post about actual gameplay or strategy. Sometimes it is fun to see alternative gaming posts, like fan art and costumes. This site has all that, plus some very decent tips.
