Please post links to the arXiv abstract pages, everyone: we don't always want to download a PDF just to read the abstract!

Edit to add: the abstract pages also often contain useful extra information, such as (in this case) a link to YouTube videos of the simulations -- https://www.youtube.com/channel/UC8ltFtaETXDphec0l-VxMsg -- or the publication history (in this case, a DOI is given).

I am of the opposite opinion. Don't post links to the abstracts as the pdf's contain them too. But the pdf's also contain figures and other things which make it easier to browse, whereas the arXiv abstract page contains a lot of unnecessary fluff.

But from the abstract it's one click to the pdf, while from the pdf it's manual URL editing to get to the abstract.

I actually started a Firefox extension that made a popup to redirect Arxiv PDF links to the abstract page, but never finished it for some reason.
