I was researching how many wikipedia articles exist for both a conlang creator and the conlang. (see end of article for list) It is uncommon for a conlang to become notable. It is uncommon for people to become notable. Lots of aspiring conlang creators think that merely creating a conlang makes them notable, even if the conlang isn’t notable yet.
In practice, people get articles when they have a significant public presence, such as being a successful author, a professor, comedian, being involved with a blockbuster movie, commercially successful game.
Sylvia Sotomayor and Andrew Smith’s conlangs are good examples of what a conlang designer can hopeful. The world notices your craftsmanship, but not necessarily you.
Now inside a conlang community, the creator still can get a lot of attention– but that attention is really contingent on good language governance. Problematic creators can be dispose, replaced and sidelined by the community, as happened in with Loglan/Lojban.
