I recently discovered the Help A Reporter Out  service.
Subscribers receive three messages every business day each of which contains about 40 queries from journalists. People who subscribe can contact the journalist to provide information or offer an interview. Any journalist can send in a query. Peter Shankman runs this, it seems that it helps promote his other business ventures and there is also a paid advert at the top of every message.
This has to be one of the best services that I have ever unsubscribed from! The vast majority of the questions are about topics that are not relevant to me – there are typically about 6 IT related questions per day out of 100+.
I would like to see a “Help An IT Reporter Out” service. It could consist of a single email per day which might have 10 questions due to a more focussed market. This would take less time to skim read which would make it more appealing to most people who are doing interesting things with computers. Then of course it could allow targeted messages related to different IT sectors (servers, desktops, PDA/phones), technologies, etc. Exporting the questions to Twitter would be good for people who like that sort of thing.
If anyone wants to start such a service then let me know and I’ll promote it on my blog.
