Scoble runs into the lack of an OPML spec:

I kept trying to open my OPML file in the OPML Editor and it wouldn’t open. I had a few complaints about that as well. I tried both the OPML file that NewsGator exported as well as the one that Bloglines exported. Newsgator’s OPML file wouldn’t even open (gave me an error) but Bloglines opened with blank titles.

I wish everyone would make their files compatible with the OPML editor, though. I’m using that a lot lately.

But it's ok - because Scoble tells us that users are king, and the format (and spec) doesn't matter:

But what Dave did was give me an application. It works. And, as a user, I wonder "if the format is so crappy, how did Dave get it to work in his own application?"

And, as a user, I wonder "why can't the developers just get their OPML to work with Dave's application?"

There's a reason for that, Robert. The *cough* spec *cough* is worthless. Every aggregator developer (myself included) has had to struggle with this since OPML came to be the standard way to exchange subscriptions. If there were an actual spec, you wouldn't see the entertaining differences between tools. So you know what? As a user, you do care.
