Shape national conversations*, sure.
A way to get data for xAI? Eh, I guess. But it's a source of bad data. Most social media is, even the best case is stuff like Stack Overflow. It wouldn't surprise me if this was at least a strong component of why Grok called itself "Mecha Hitler".
Huge success? Unfortunately I have to agree, given the US government still ended up integrating it despite the Mecha Hitler incident.

As with all of these things, I have to ask: How confident are you that it's telling you true things, rather than just true-sounding things? My expectation is Grok will be overtraining on benchmarks (even relative to the others, who will also be doing so at least a bit), and Grok's benchmarks will include twitter reactions, and it will be Goodhart's-law-ing itself in the process to maximally effective rhetoric rather than maximally effective (even by the standards of other LLMs) "truth-seeking".
* plural, not "the", it also works in at least the UK as well as the US
