On my homepage I have a 'Latest blog post' section showing excerpts from my most recent posts.
My posts feature text in bracksts  because of a plugin I have.
I don't want this text to show in the excerpt on the homepage as it doesn't really make any sense to the viewer.
You can see an example of this at my site mrbluelips.com. The text I want to hide is "Podcast: Play in new window | Embed" as shown.
