Regarding the title of the slice, the title will be whatever is encased in class=”entry-title”. And you happen to have your class=”entry-title” wrapping dynamic text. You can change this by wrapping text that doesn’t change. Personally, I like the changing title.

Regarding uptake. I guess that remains to be seen. Personally, I don’t have many that I use, but i would use some if they existed, a techmeme one for example. Time will tell.

Regarding embedding, it sucks a little that the standard embed code for youtube is in low-def. If you view source on my blog post, and take the embed code from there, I’ve got a little hack that forces the embed into high def. Sucks, but thus is youtube embedding. Not many services that support high def and those that do (eg vimeo) don’t support highdef embedding (for free)

And what, you didn’t get tempted with IE8 for the mardi gras webslice – it’s the first commercial webslice with silvelight in it you know
