Comments on posts

There are multiple reasons why I don't post comments on blogs:

• the blogger has written so comprehensively that nothing more need be said
• the blogger has written so comprehensively that it will take my feeble brain time to get my head around the subject and even then, it probably won't quite get there but I feel proud to know such brainy people
• the blogger has written so comprehensively that to say "well done" sounds lame and patronising
• the post may not warrant a reply (like the get yourself a ridiculous title one below)
• lots of other people have commented and I don't really need/want to
• lack of time
• (very rarely) I don't agree with the blogger and I don't really want to start a discussion about it
• the blogger in question is my husband and I feel like I always comment on his blog
• I have been the first to comment for the last three posts of that blogger and I'm starting to feel like a stalker
• are there any more to add?
