The Directory of Open Access Journals (DOAJ) has announced a new interface, which can be seen at www.doaj.org. There is a note about the new interface here.
Also, in a posting to the American Science Open Access Forum, Anna-Lena Johansson from DOAJ notes:
"Now there are more than 6300 journals from more than 110 countries in more than 50 languages in the DOAJ. More than 2500 journals are providing metadata on article level, which means that more than 500,000 articles are searchable from DOAJ."
