Where are my commas?

Or other punctuation marks? Will be busy today shoveling out of the snows that gave us a white post-Christmas:

Blogging is always a hit and miss during this time anyway.  But I will ask this - where are my punctuations?   It's tough enough writing when you aren't a trained writer.  But I know I place certain punctuation marks in my posts, only to see them vanished upon publication.  What's happening?  Anyone?  Thanks.
