Do you mean the FB PHP SDK? or is the apk like an app kit?

I've never messed around with it.

I took a VERY cursory look at some API stuff from another site. Doesnt look that confounded to me. At least, no more than many others. In comparison to the Windows various API's it looks simon simple from my cursory glance.

Alot of webby stuff appears like it might be complicated but the lions share of complicated tends to be larger scale stuff. Like eBay, auctions are not really too complicated but due to numbers of scale and all the support function it becomes a monster. Like Amazon for example. Amazon categories are broken down to stores. Quite independent though share many data structures. Its due to scale. PrestaShop lets say trying to deal with just one Amazon category, handbags, would fold up shop in less than a second due to sessions hitting it. Enterprise applications are always distributed applications or they just cant handle load.

But in all reality, the old Frogger game on your Playstation one is a more complex piece of software than whatall, Prestashop or Jooml'r. Something like iRacing online, THATS complex.

Having not messed with facebook coding at all what exactly are WP features people would use?

Like/Not obviously, posting to and from? Familiarize me with what capabilities WP'rs would want in a plugin / widgets and perhaps can get it done. Then on Friday when we meet at the pub-ski I can run it past em'. Dunno if he'd be interested, perhaps a "Buy him a beer" license as I'm sure he'd like that. LOL.
