Make sure the cron is set up properly. Enable logging and check for 'Running cron' entries.
WP-o-Matic attempts to override the maximum execution time setting by its own. In some setups, however, this is not allowed, which causes WP-o-Matic to exit unexpectedly when fetching large feeds. You can try changing this setting via the .htaccess file or by contacting your hosting provider.
Use the post template feature -located in campaign settings-. For example: {content}
Because the feed you're using is only syndicating excerpts, not full content.
This is a limitation that will soon go away. This, however, does not create extra overhead, and you feeds will be fetched in the timeframe you specify. We just make some extra unnecessary queries to the db.
Campaigns give you the ability to group feeds and select common options for them. So, if you ever decide to change a setting, all the feeds in that logical group will be affected.
The best way to organize your feeds is up to you.
