Occasionally, spam accounts trying to peddle something sign up for the RePEc Author Service. We watch out for them, but if we missed one, do tell us, as for anything amiss you may notice.

Interesting that my Bluesky account and my bridge from Mastodon are very far apart.

Once again, monthly RePEc statistics are delayed as we struggle with weeding the abstract view numbers. While we do apologize, we also blame AI sites for this.

I actually and seriously want to know how to improve. I get very little constructive feedback, so it is very much welcome!

Christian Zimmermann @czimm-economist.bsky.social · 14d

I beg your pardon. We make it possible for small players to get their works disseminated, which is actually the impetus and still the goal of the project, quite the opposite of what you claim. All services are free and no one gets privileges.

I only use it for code translation, so it may be specific to my use case.

Yes, but it also has a tendency to be lazy ("and continue following this pattern") and skip the hard parts, sometimes without telling. Verify everything!
