Not the worst idea
To be honest, if they came back and offered a decent search engine and a little less aggressive data harvesting, they might have a chance.
But I seriously doubt it
Yahoo! – the outfit that dominated the web in the late 1990s before Google ate its lunch – is plotting a return to the stock market. The Purple Palace's CEO, Jim Lanzone, on Tuesday told the Financial Times that Yahoo! is "very profitable" and has "a great balance sheet." Yahoo! fined! $35m! for! covering! up! massive! IT! …
I guess their front page is useful if you're a doom scroller, now that Twitter is basically useless. The comment sections will get you all the hateful right wing conspiracy nuts you can stand. My only use for is as said before, a free email I can use to sign up for stuff without filling my main one with all the junk.
I don't know how relevant it is, as far as I can tell it out sources its search to Bing. Beyond that it's an ad slinging news aggregator and web email provider. It's a shell of its former self, the corpse of a former tech giant that's being passed around. Verizon played with it for bit got tired of it and sold it to whoever owns it now.
Yahoo Groups still has some activity, I suppose.
Yahoo Mail has users who are stuck on it because their long-used addresses are there and it's holy hell to change email. But it has gone from bad to insanely awful. Their IMAP now limits you to 10,000 messages; all older ones disappear from IMAP and are removed from your mail client if it uses IMAP sync, which is alas the usual. The messages however remain on their server visible to the webmail, and their advertising harvesting no doubt, but that doesn't provide an easy way to go through thousands of pages' worth to locate stuff, just a rudimentary search function. The mail store also manages to break most POP clients. It sort of portends what Twitter might look like after a while with nobody left to maintain it either, though email is more important to most users.
Isn't their search just reselling Bing? The home page looks like a ladies' magazine, lots of gossip.
