Here are some interesting Joomla blog posts I found during week 39.
There's a really nice post about Joomla 1.6 caching and Brian Teeman talks about meetups at Joomla!Days and about the spending of Open Source Matters funds.
The October issue of the Joomla! Community Magazine is out, and PC World talks about eBay using Joomla, just to mention some of the notable posts from this week.
Have a great week!
