Even if you jump into a thread you haven't read before, you can still skip to the latest page. Eg. if you looked at June 2014 Blooms thread now, it has over 500 posts and would be a hassle to read through all of them (although I did
).
You can just click on the last page, I think it's 26 for me, since I have my preference set for short pages, and start reading there. They are the numbers in the boxes at the top of the page. Then if you catch up every day or two, you can see everything without having to wade through thousands of pictures in 500 posts.
That being said, I can't scroll past a picture of any daylily to save my life. Gotta ogle them all.
