Re: activity stream post ID?
p.s. @hoodiemark – in answer to your second question. I don’t think a filter is a good way to solve this one…
We wanted to avoid displaying post content for blog posts in the activity stream.
The filter options only seemed to let us control how the activity for a blog post was created in the first place, not how much of it was displayed in the stream.
If we’d used the filter to stop the ‘unwanted’ content being added in the first place, it would have meant it was also unavailable in places where it was wanted (e.g. the blog post widget seems to rely on the activity template).
I hope that makes sense!
