We believe XenForo has great potential and we are interested creating addons for XenForo. As XenForo SEO optimization is done , it is not feasible for us to create a SEO product. However we may create other products for XenForo in future.What do you mean by that? Care to elaborate?
Completely agree.The SEO in Xen is done the proper way. One .php file feeds one server rewrite rule with anything that needs to be SEO'ed (forums, threads, members, etc.), creating minimal server impact. You can SEO pretty much everything in your forum or other adjacent products, using the available process. Now, that is what I call efficient code.
