Reddit is in theory the same.. but it also is loaded with spam, in the form of ads paid to reddit. This is worse.

Compare: FPGA group on USENET, very little spam: https://groups.google.com/g/comp.arch.fpga

Reddit, full page animated old-spice ads: https://www.reddit.com/r/FPGA/

Also as much as you dislike google groups, just compare the UI of the above two.. ugh.. of course there is old reddit:
