Just heard about this via Post Status.
From the website:
LoopConf is the greatest conference ever created for WordPress developers. LoopConf came about as we heard technically-minded folks talk about wanting to get together and dive deep into advanced engineering and development topics.
The speaker lineup looks stacked so far, including @syedbalkhi. All listed on the website linked above.
While dev tracks at WordCamps can get pretty advanced, a focused conference on solely development-related topics sounds intriguing.
Will you be attending?
