Hm, Eddie, I have the feeling this discussion is based on your own needs and demands on a photoblog. Be sure that there are many purposes why people set up a photoblog, not only show photos in a nice environment. This is the reason why there are so many templates outside and why there are so many addons available.
We have been asked quite often why we don't include this or that Addon into Pixelpost core code since everybody seems to use it and the actual language theme is the same discussion in the end.
Pixelpost is meant to provide a basic installation which just fits the minimum needs of everybody who wants to get photos published in the web on a daily scheme: An admin panel for uploading and listing photos and for doing some settings, not much more. And a front side where people can see one single photo and an archive.
Additional features like comments, tags or RSS were included in the past versions as well as multilanguage capability because there was the demand of a big majority of the users.
But everything else will and should stay an optional extension since not everybody might need it. I even think one step further, reducing Pixelpost to the absolute minimum in 2.0 basic installation and doing everything else as Addon (tags, categories, languages, RSS and even comments) which come with the installation package but can be turned off if not needed.
I think the future Pixelpost will be some sort of modular concept: the core code which everybody needs and modules for extending it up to personal needs. And a lot of Addons and Templates provided by our eager users to extend Pixelpost to whatever you want (but I am afraid it will never take photos for you ;-)).
