There is something I thought of recently, as a categorization scheme:
the weblog-macro includes the parameters
1: amount of posts to show
2: the actual weblog snip (optional)
How about having a list of weblog snips to grab the items from. With this mechanism, you could have several weblog (already supported) with a subset of them syndicated e.g. on the start snip. If an editor then clicks on the "post blog" link, he should be presented with the choice to actually post his entry to one of the configured weblogs.
Another small point would be to redirect edits of weblog entries to the weblog entry form and not the general snip editing (=> separate field for title).
If I can migrate to your version of SnipIt, I'll try to work on that.
Where do you see your version in contrast to the newly launched SnipSnip project on sf.net?
