I for one completely ignore some board topics such as
lawn care; I live in the desert, haven't had a lawn in over 20 years. Since my dog of 13 years died a few years ago I have not replaced her and have no other critters, so I ignore critter care. I haven't been growing much as I split time between desert and mountains and it just doesn't seem worth the effort at this time (I use the growers markets), so I mostly ignore those topics.
I do read the homesteading, building and
energy topics as well as woodland care and would rather not have to do my own sorting as I look for those related posts. So I am happy with the status quo.
I skim down the list of topics, right click and open new tabs on those I wish to read, then click the "mark as read" down at the lower right of the first page. The next time I login the topics with new posts are indicated and I can decide/select all over. It works for me. OMMV.
Anyhow those are my thoughts. It would be interesting to here from others who may follow selected topics or who read the whole forum.
