The most important improvement even if users dont think so is your SEO.
I have heard many many users complain about these issues. I have seen many users leave oxwall for this reason.
The time has come please drop everything and work on these 3 issues asap.
W3C compliance
Alt tags
html micro data
We all want oxwall to succeed but if you can not make our sites able to be seen or found then we are all wasting our times. Telling all users to modify their script to the standards of google is unacceptable. That is why we have you and have taken an interest in your project. If we were able to code these things our self's we wouldn't be using this software we would be making our own.
Please make your users happy. Please implement and have these 3 things working in 1.8. 3
