You shouldn't ever be afraid to comment :)

As long as your comment is a response to the post, adding to the conversation or letting the author know that you read the post - it is all good!

I know I mentioned "Basic Comments" like "great post" and "nice" - I am not hating on people that use these on occasion but when they are used all the time (like a broken record), or if I see them posted on 50 other posts a few seconds after and before the comment was made on my post - the compliment loses it's thunder lol.

Thanks for your Genuine Comment and question - it shows me that you took an interest in the topic of my post, and I appreciate you taking the time to read it :)
