NOT "This week in Diffusion we..." because all people will see is "This week in Diffusion" every single week. It sounds good on radio, but it is a bad headline. We have only 38 characters, so get creative!
These headlines are grabbed in RSS and syndicated all over the web, it may be the only link to the podcast people see, so it can't be "This week", and it can't be so long that it gets cut off and makes no sense. Have a look at the rotating headlines on http://www.2ser.com/programs/shows/diffusion/ Some versions show only the first line. Imagine if it kept changing from "This week in Diffusion" to "This week in Diffusion", nobody would click on it. The information is lost.

These should be something close to what the feature writer/producer has written in their intro. Sometimes its remembered differently to what the writer said they intended, or only a small part of what they said is over-emphasized. Certainly if I've written that you've said something that you didn't, then you'd be annoyed, so its good to be sensitive to that. Keep it short, punchy, attractive, but also accurate. Our old style blurbs have been pronounced un-readable by some of our audience, and we need to change with the times.

First names or no names are not sufficient - people don't know who we are unless we tell them.

All credits should be given. Sometimes producers accidentally leave credits out of the blurb altogether.
