You probably have fixed it for most, I'll give you all the specs I can remember, and it might just be on my end,
- I almost always hit post draft before I ever put a blog to live, so that's the main difference I notice between most blogs I post and this one, so there's that, as for any other details:
- Typed and tried to post this particular blog on a Dell Optiplex DX260 tower running XP; I hear XP is no longer supported, or won't be soon, so I wonder if whatever you're using to back up blogs just isn't communicating properly with the OS, or Mozilla Firefox, which is the browser I always use, both on that PC and my Dell D620 laptop also running XP, which I'm on now (I have to tell this thing to use Flash always for every website I go to, cause my version is out of date, but if I upgrade, I get sound with no picture)
- It had one picture sent from from my phone to my e-mail, then copy pasted here that had sort of half-sent (half the image was there, other half was grey nothing when I received it in my AOL); a signed Blue Man Group Playbill, next to a Fenway Park tour ticket were first two images; then paragraph text, then side by side DK64/1080 Snowboarding box images from Google Images, then paragraph, then 1080 screenshots, then paragraph, then F-Zero GX screenshot and F-Zero AX arcade machine pic, also Google Images, where I usually use Bing, then another bit of text, and I think that was it. All images were copy/pasted, did not have image location copied; no idea if that makes a difference, my copy/pasted images still seem to be up in a previous blog, but it's unusual for me to just copy/paste ... why, I don't know.
That's really all I can remember. Either way, it was a short blog, and I imagine any blog site can have this hiccup from time to time, might be something I did I'm forgetting, and you guys are doing a lot better for me than 1up ever did, so don't feel down. 
Edit: The blog actually posted with my title, but all of the content was gone. I deleted it, as I was taken to the place to comment on the blog, so I figured it was done for. Maybe I should have said "edit the blog" before being so rash, I dunno.
