First off, the next major version of pixelpost, aka Pixelpost v2.0, will be a complete rewrite. And I think one of the major selling points for this, will be the fact that it has LESS features than the current version of Pixelpost. Less features you say? No way!
Let me explain, yes, the core Pixelpost product will have less features, but it will have various addons which will add those features back, on an individual basis, if you need them, features such as tags, comments, categories, etc. That way if your photoblog design doesn't use comments, you can literally remove all the comment code, spam filtering code, all the admin panel comment options, etc. So you're photoblog will remain super small, and super fast, and only do what you need it to do, nothing more, nothing less.
That's the idea at least.
