Just found out about a freaky and cool new tool called Jane - the Journal/Author Name Estimator. For more on the approach see this paper in Bioinformatics.
Here is how it works -- you paste some text into a box and you can get the tool to suggest a journal that is most suitable for your work. Or you can have the tool search for an author who is doing work similar to what is in the text (this is useful to find reviewers or papers to look at)
One thing I like about the journal tool is that it highlights which journals are Open Access and which are deposited in Pubmed Central. I have tried it out in a few different ways and it seems pretty useful. So if you want guidance on where to submit a paper or who might make a good reviewer of a paper, check it out. It seems like it would make a good tool to help reporters find someone to interview too.
