I have seen a lot of "Case use" type post regarding steem and the tribes and the steem engine coins. I feel that there are a few different type of content producers, content users and just viewers on steem block chain.
People with a real "Blog" need to remember who their audience is on that blog and try to not mix their alternative "Post" with the blog. Like how you keep your excelclub separate from the everyday social posting.
I find business type Blog's to be pretty limiting, and generally based on one subject, that being said however, if I want to find information about Excel that would be useful to me I will look for an Excel blog. (Which I do on occasion, we all have spreadsheets for this or that, and forget because we don't use them often, so we go to the pro's). Yes the Business blog's may be a bit dull, but they are useful, useful if they are not filled with a ton of off topic stuff.
The Entertainment Blog's, I like those I visit the art's the music, and photography post a lot. They are one type of content that I personally enjoy, and you get to meet and chat with the writer's the artist, the creators, and some times you can get help on your chosen hobby of the time.
The Everyday Poster, This content I also enjoy, but I like for it to be in its own area, I know a lot of the writers, the painters, and a few of the photographers, and other creative types in the Entertainment Blog arena will sometime clutter their Entertainment Blog's with personal stuff, it makes it hard for me on occasion to distinguish between what the content is when mixed, so keeping it separate , like a business blog is best.
Me I am an occasional "I have this to share", today type poster, I am not an entertainer, not a business blogger, not a professional blogger of any thing, just a social animal sharing, There are all kinds of blogs on steem, some I can go to and know what I am going to get, or go to and find help with a thing or two, some are like mine a big mis-mash of jumbled post, but i also like that kind of content.
So yep, people need to think about what they want, expect out of their blogging, are they a blogger, do you want to blog, or do you like me just want to share an occasional thought or item of no real import? People will still visit and view no matter how people set about their posting, it is just that some are going to get more eyes based on the over-all feel of a persons blog.
I love how you have broken down the blog types.
Using the Excel blog as an example, thats the searchable type content that steem needs, simply because people actually search for it. Traffic grows over time. On traditional media, Entertainment is more sharable/viral type content and traffic dies over time.
Expectations are an important factor in all of this. I think the personal blogs are doing well because the steem community have had a hard time, but we have stuck at it and we have moved beyond content creators to a close community.
