Simple Gallery - The next phase

Been thinking a lot about my Simple Gallery Management Project.
So far, it's been downloaded ~200 times (130 for version 2.0), and after implementing ~6 projects with it, I'm thinking about taking it to the next step, and making it an even simpler, more generic CMS.
This means generalizing the database, redoing the management portal into a cool, hierarchy-like content portal.

I'll still be using HTML/ JS/ PHP (For json API)/ MySQL as a platform, simply because the cheapest hosting services are under that platform. I could implement it with node.js and mongodb, but that would be overkill. Only when I implement a simple social network, then I might use these platforms - There are few services (Like dotcloud) which do node.js and mongodb hosting, and they are not meant for the SOHO customer requiring our services (myartichoke).

This also got me thinking - What about social networks? Does anyone really need to implement a social network anymore? The 2 major risers in the social network battlefield these days (instagram and pinterest) are less about social, and more about sharing and following, rather than full fledged social networks. This means that these social networks have the 'core' social features (contacts, feed, responses and likes) built into them, but not much more - Facebook and Google+ have a whole envelope of features which try to integrate the web into their sites.

Of course, all these networks also have RESTful web services, allowing for third party developers to integrate into their network as well. This has also become a common practice.

I've also considered multi tag support, but came to realize that I'm using this feature as a 'category' (news/ objects/ shows etc.) when implementing sites - That is why I'll probably change 'tags' to 'categories', and maybe add multi tag support later.

In scope as well is making the GUI a little more '2d' and consistent. Adding an integrated toolbar per item (Like twitter's), maybe convince my wife to design some buttons for me :))

I'll update soon, once the new version begins to show signs of life.
