Awe Yes Wordpress started off as a blogging software mainly for chicks- Not anymore. As a social script can indeed turn WordPress into a CMS. Think Buddypress or Peepso. I own 3 WordPress sites and they all rank very high in SEO. They are all pretty much written in PHP with a little java & ajax. My opinion is the major downfall of WordPress is it is slow. In defense of my new OSSN is the fact that if you google my site Social Hobo, it appears as high as possible. First link on the first page in google's search . And it is way faster loading than any of my WordPress sites.
David I think your idea of crossplatforming is a good idea, but it would come with more problems. Although Peepso did it to compete with BuddyPress and they even cross-platformed MyCred points & badges and learndash.
However since those are third party plugins Peepso will not offer support for another developer's plugin and I don't blame them. Another thing to consider is the fact that Peepso has more than two dozen developers working for them 24/7 across the world. And their software is very expensive. They priced me out of their software as I can no longer afford them that is why I have switched to OSSN.
I am not sure how many are working for OSSN but I do know that Arsalan works very hard and he has a lot on his plate. That is not to say that it is impossible for OSSN to incorporate a cross-platform to add some worthy WordPress plugins. However it would be a lot of work and they would need to get paid. David would you be willing to pay OSSN extra money in this case? If so how much more?
