Using wpomatic to build an autoblog .

I need to be able to find feeds for a specific term such as "jack kennedy" etc

Since the subject is very narrow following the general rss feed of a site is useless. I need to only find post or feeds that contain this exact term.

Any ideas of a fast way to go about this?

You could use a Yahoo Pipe and take the RSS output to use with wp-o-matic. On the Yahoo Pipes you can search for pipes for searching various search engines for keywords.

Here are a bunch of pipes that do searches:
http://pipes.yahoo.com/pipes/search?r=tag:search

Usually the pipe will prompt you for search criteria and then you run the pipe. After running it, you can click on Get as RSS to get a RSS feed for that search. That is the feed you add to wp-o-matic.

Google: "rss+feed your_niche"

there are lot of information you can get from the site - whatisrss and wral.

In wral if you search with "jack kennedy" you will get lots of such things.

Stop cutting corners, just rest of fresh content because like you said it's quite a
"subject is very narrow" is only a matter of time before Google Nukes you all to blog
with Panda updates etc.
Google don't like Scraper sites your about one year to late my friend. Don't get me wrong
people still have success with them But if you are a newbie then just forget about it.

Or you could use a combination of fresh content and autoblogging. Panda was mostly directed at very specific sites like ehow, as far as I can tell it has had little affect on autoblogging.
