Every week on Learnable.com, they feature a live question and answer chat session with one or more people involved in the web development industry, centered around a specific topic. It's absolutely free, and you can join in on the chat sessions and ask the guests questions.
Access to the chat room opens 15 mins before each session.
Last week's topic was
PHP. Next topic will be Mobile App Development, which may be of interest to anyone considering or currently involved with developing apps for mobile devices.
You can sign up for email reminders and receive emails announcing the next live chat.
Transcripts of
past chats are available on sitepoint.com.
DISCLAIMER: I work for Sitepoint/Learnable, but I am not paid to advertise for them. (I work in customer support) I just thought you guys might be interested in this, and I didn't want to keep the info to myself. :-)
