I agree with you.. but there is a lot of issues related to blogging that has caused it's decline in popularity. (I.e. content aggrigation, cross connection social comment features, reduction of spam in discovering/blog reputation, etc)
For me I have a blog but I'm struggling to write for it because I don't have an audience that makes the blog valuable for me.
I have written a dozen blog engines in whatever language caught my fancy at the time. In the end I realized I'm writing my blog for myself, not for an audience. The value is in sorting my mind, not someone reading what I wrote. I have moved off online publishing since then. Now I just journal in Zim desktop wiki or even on paper and you and I are better off for it. I'm just guessing, but maybe question your desire to have an audience.
i've had dozens but just write for yourself. I find it hilarious and humbling but the most enjoyable is ironing out the inconsistencies or gaps in my own thoughts. Have the cake or eat it? It can be left as an open question too. Asking the right questions is useful.
You call them issues but I prefer to think of them as a filter that keeps blog content high value exactly because it discourages those who are not primarily interested in sharing information but are after some other goal.
I wrote a little blog program because I find the blog format (articles sorted by date) convenient for reading about things someone did, so I figured when I do things I should also put them in that format. But it turns out I don't do a lot.
