They killed reverse image search for Lens, which is borderline useless.
Image search no longer has its date range filter. You can still use the undocumented keyword, but who knows when they'll take that away.
Search results are increasingly irrelevant. Yesterday, I was searching for news articles about the late 00s capture of an Al Qaeda leader who was tracked down in an unusual way. Amongst the results were Visa's careers page. (As a side note, I then asked ChatGPT about the event and it hallucinated in all 3 of my attempts.)
I've archived 100s to low 1,000s of my own personal contributions on a few online services to both sites.
For Archive Today, it is possible to expedite the archival process by generating the initial submission URL, though you'll have to complete another two steps after that point manually as I recall. If you're archiving a large set of sites, you can compile a list, generate a Web page off of that, and work through it at a pretty good clip.
