The Directory of Open Access Journals (DOAJ) now has more than 1500 peer-reviewed open access journals. This is an impressive number, which is a great witness as to the vibrancy and power of the open access ideals. The main success of OA is that it empowers authors, who will usually get ot keep their copyright. It encourages the reuse of articles, and does away with the ludicrous economics of traditional academic publishing.
If open access keeps going at this pace, traditional publishers may start to find that they cannot continue pricing journals in the same way. After all, we academics do all the work for them!
