Yes, daily blogging can be overwhelming... I know that it is possible, but it's hard to keep pace, especially if you want to engage with others, reply to the comments, etc... Very often, I get comments on old posts, which is additional work to reply to, respond to, etc...
And you are right about posts without comments... When I do curation for @Ourpick, very often I see that picture... Those posts are usually some regurgitated news, without added value... So, I suppose that there is nothing to add to it...
Thanks for adding value to the post! :) Have an awesome weekend!
