I can see all posts at once, private and public
fluctuating screen size
font size (my beef with this is complicated. just trust me.)
2 ways to subscribe
the post is visible in the same window when you comment
it's hard to make it as pretty (but that's probably only because I haven't started using Xanga Themes yet...)
blog archive feature is real nice to have
automatic save (Xanga only has a manual feature that will let you save without posting and if you lose the page suddenly, you will have lost whatever you didn't save... and it will be posted prematurely. so... if this happens a lot, set it to private until you're ready to post. big deal.)
RSS feed for the comments
stuff I thought I'd like better about Blogger:
"only sign in once to get to my e-mail, RSS, and blog." well, they've taken the blogger link off of the Google links header. plus Xanga is letting me stay signed in even when I open a new window (they didn't used to) and I only have to click once to get to my home page. Blogger requires two clicks (or three, plus search and error time, if you're trying to get there just with the Google links). I mean, big deal right? but it's frustrating to me somehow.
"easy side page elements." not any easier than it is to enter the html in the Xanga Look and Feel box. plus Xanga has that same feature, again, in the Themes department that I haven't gotten into yet.
"attractive format." sure, but I can't tweak it without a technological pick and shovel. Xanga lets me in on the action and I can change the look in subtle ways as per my preference.
"RSS feed." yeah, Xanga's got that too, now.
I think it just depends on the user's individual needs and preferences. Personally, I'm thinkin' Xanga.
