Hi,
figure and figcaption (HTML5) seem to be very popular:
-Clear semantic relationship between pic and caption (good for search engines)
-Not only for pics but all kinds of figures
-Easy CSS-styling
-Easy grouping of figures, for example creating galleries
Since WP 3.4 WP hat its own caption feature.
Are there still good reasons to integrate figure/figcaption instead of using the WP default feature?
