I'm trying to set up a [planet of my users' blogs](http://help.schmonz.com/planet/). I've enabled the aggregate, meta, and tag plugins (but not htmltidy, that thing has a gajillion dependencies). `aggregateinternal` is 1. The cron job is running and I've also enabled the webtrigger. My usage is like so:

    \[[!inline pages="internal(planet/*) show=0"]]
    
    \[[!aggregate
    name="Amitai's blog"
    url="http://www.schmonz.com/"
    dir="planet/schmonz-blog"
    feedurl="http://www.schmonz.com/atom/"
    expirecount="2"
    tag="schmonz"
    ]]
    
    \[[!aggregate
    name="Amitai's photos"
    url="http://photos.schmonz.com/"
    dir="planet/schmonz-photos"
    feedurl="http://photos.schmonz.com/main.php?g2_view=rss.SimpleRender&g2_itemId=7"
    expirecount="2"
    tag="schmonz"
    ]]


(and a few more `aggregate` directives like these)

Two things aren't working as I'd expect:

1. `expirecount` doesn't take effect on the first run, but on the second. (This is minor, just a bit confusing at first.)
2. Where are the article bodies for e.g. David's and Nathan's blogs? The bodies aren't showing up in the `._aggregated` files for those feeds, but the bodies for my own blog do, which explains the planet problem, but I don't understand the underlying aggregation problem. (Those feeds include article bodies, and show up normally in my usual feed reader rss2email.) How can I debug this further? --[[schmonz]]

>> Thanks for the quick response (and the `expirecount` fix); I've forwarded it to David so he can fix his feed. Nathan's Atom feed validates -- it's generated by the same CMS as mine -- so I'm still at a loss on that one. --[[schmonz]]

>>> Nathan's feed contains only summary elements, with no content elements.
>>> This is legal according to the Atom spec, so I've fixed ikiwiki to use
>>> the summary if no content is available. --[[Joey]]
