Tried this for a while the last time I saw this posted somewhere, but went back to using tail.
Using less +F you're not able to add blank lines to the terminal. Seems kind of silly, but it's very useful to see if there has been any output since last time you took a look.
This is exactly the reason I've never switched to using `less +F`, as well. When I tail a log, I'm usually looking for sections of it corresponding to particular test runs. Adding blank lines or even rows of dashes/equal signs lets me make the distinction clearly visible.
