Missed opportunity - giving Carrie a sex columnist rival

Since the narrative is carried by Ms. Bradshaw's inner dialog that sort-of-maybe conveys her in universe articles, I always thought a way to show off how in demand she is as a writer, would be to give her another writer to be compared to.

Until she lands a column at Vogue, Carrie was never seen getting any true work critique (or even having to show up at the office of her fictional paper, right?). Imagine if PR maven Samantha got hired by a new women's interest magazine and has to promote a rising columnist who is applauded for having a more with the times sex column. The new columnist's work is racy/titillating and makes Carrie's rhetorical question stream of consciousness articles look like someone who doesn't "know good sex" as the bus ad proclaims. Any thoughts on why Carrie was never made to rise to the occasion and show that her writing was unique and inspiring enough to secure an audience that she was never pushed out of the industry?
