Besides one's interest in a specific model/forum, do you have your page set to show Today's Posts or New Posts?
Easy to set, hit and see what new posts have been made and what's going on across the forums...I read the E53 forum of course, but I also read all the New Posts/Today's Posts in all forums, to see what other posters are involved with. It broadens the reading and most of the stuff in all forums is interesting, imo.
If one likes poetry, looking for Lake Poets, (Wordsworth, Coleridge, et al), or Great American Poets, (Whitman, Frost, TS Eliot, et al), is not the same at looking at all the General Poetry forums
If you read all the New Posts/Today's Posts already, then toss this post.
