I've just noticed this beginning to show up today I think....
Something has perhaps changed in the code layout and the RSS feed layout for the Logos Blog.
Formerly blog posts would come to my L4 home page without the word TWEET starting every post.

It's not the biggest deal, but with all deference to our little blue birdy friend, I don't think it belongs there, especially as it's unclickable and just a touch unsightly.
