For me it's not the "tons of work" it's that I've shared something, I'm thinking, with people out 'there' somewhere, and so when you don't get get any 'comment' responses then you're not sure, and it simply doesn't feel like, you've actually shared anything with anybody. I write about things that matter to me, very frequently things that I am passionate about, things that I desire to share with others, so, it is kind of no fun when they seem to just sit there and fad away. When you check the 'stats' and see that a hub has been visited 30 or 70 times with no comments, even if there are a few 'awesome' or 'interesting', etc, tallies, you don't know if dozens of people look at the 1st paragraph and left or read the whole thing and didn't car for it.
But, I'll tell you the thing that really, I'll say, confuses me . . . the last hub I published was on Blues music, the significant role it's had in the development of American popular music, etc, etc, and I've gotten one comment (thank you tlmcgaa70) and view visits. Now, Blues is something I am passionate about and I realize many people simply aren't, or actually have no interest in it whatsoever - but here's the part that's difficult for me; when I see all these comments popping-up on hubs along the line of 're-grouting your bathroom' or 'how to properly tie your shoes', I do feel a bit frustrated.
Please don't think I am in any way mocking useful 'how to' type hubs or at all disparaging those who comment on them, that's not my point at all - it's only that, when you've written and published something from your heart, something you seek to share with others, it can be a bit discouraging no one seems to see or care about it if they do see it.
