Note: The plugin Topic Storm has been retired. There are no plans at the moment to revive it.
Topic Storm, “The WordPress autoblogging plugin with a Twitter Twist” has just been upgraded to version 1.2
The new version introduces W3 Total Cache and WP Super Cache compatibility.
These two caching plugins are well used with over 306.000 and 2.1 million downloads respectively!
Previous versions of Topic Storm did not trigger an update on websites that use above caching systems, meaning posts would not always be immediately available. The new feature introduced in Topic Storm 1.2 forces an update in the page cache on sites that use either W3 Total Cache or WP Super Cache.
Thank you Santiago for suggesting the cache plugin compatibility feature
The Best WordPress Cache Plugin?
Personally I prefer and recommend W3 Total Cache.
There are cases where alternatives provide better solutions, but it is always the first WordPress cache plugin I test on any WordPress installation.
