I finally get what you're saying and I completely agree with you!
Too many stations jumped on the Jack FM bandwagon, or worst the Free FM bandwagon. Also, a bunch of stations jumped on the Movin/Rhythmic AC bandwagon last year without doing their homework. The previous year too many stations jumped on the Reggaton/Latin Urban bandwagon.
It's sad that no one has the balls to bring a true CHR back to San Francisco, Baltimore, Denver, Vegas, and Norfolk. I mean the CHRs that were there were definitely not struggling as much in the ratings as many of these format of the day formats do. Z-95.7 and its Top 40 format gave the 95.7 FM frequency some of its best numbers. 95.7 Kiss FM Denver performed way better as a CHR then it did after it flilpped to Reggaton, or its current Rhythmic AC format. I don't remember B-102.7 doing too bad in Baltimore, or 101.9 Kiss in Vegas. These stations just needed to make some ADJUSTMENTS to their stations, or be given more time to succeed. Look at 103.5 Kiss FM Chicago - it's doing pretty well b/c it was given enough time, was finally given a local morning show, and was given the right PD (the legendary Rick Gilette who used to prgram Power 96 WHYT in Detroit back in the 80s).
San Francisco's CHR was owned by Bonneville, which perhaps is too conservative of a company to do CHR. They also had Z-104 in Washington. When Z-104 left the DC airwaves you had Hot 99.5 come in, and look how well its doing. Again, they have the right people in place Hot 99.5 and Hot 99.5 is a very balanced musically for a major market, in a market where people thought only a Rhythmic CHR would work.
In Norfolk Z-104.5 did well both as a CHR/Pop and a Rhythmic CHR in the 90s (it constantly flipped back & forth throughout much of the decade), but since it's settled on its Rhythmic sound the only CHRs to come and challenge it were on weak signals.
The good news is that Rhythmic outlets like Wild 94.9 San Francisco and 98.5 KLUC Vegas have been moving a bit more towards CHR/Pop lately. Rhythmic CHR fans have other stations in that market outperforming these stations.

The most Pop leaning of the Rhythmic stations though is Jamz 96.3 in Albany, despite the fact that there are already TWO other CHR/Pop stations in the market:

There's also some Hot ACs moving towards CHR. Q-102 Cincinnati has been straddling the line between Hot AC and CHR for years (same way B-100 San Diego used to do in the 80s). Now there are other stations with a similar sound. In California's Oxnard-Ventura market KFYV Live 105 could be classified as Adult Leaning CHR/Pop. It's the closest thing to a pure CHR that this market has seen in decades:

Compare that with Cincy's Q-102

95.1 WAYV Atlantic City, which was a CHR in the 90s, is a Hot AC that has been shedding off its 80s library, and adding more Rhythmic hits instead. The few 80s titles it still plays are usually Hard rock hits like Guns N Roses "Sweet Child O Mine", Bon Jovi's "You Give Love A Bad Name", and Def Leppard's "Pour Some Sugar On Me", records that still have some youth appeal.

Some Hot A/Cs seem to be experimenting with CHR at night, like Q-98 in Fayetteville, North Carolina

I think it's getting a little easier to evolve towards CHR/Pop right now with recent hits from Maroon 5, Fergie, or the new one from Rhianna (Shut Up And Drive) having a very pure pop sound that fuses Rhythm, Pop, and Rock.
