Google: Please fix Gmail's broken threading model

I'm going to keep posting variations of this every 6 weeks until Google surrenders.

Dear Google,

Gmail's threading model was a cute idea. I suppose it would even work if you hadn't hidden subject lines in threads, thereby promoting subject line reuse and thread metastasis.

It doesn't work. Honest. One day you'll agree with me.

As a compromise, let me change the subject lines in the messages people send me (Outlook's killer feature). If you like, you can propagate the new subject line down the thread.

Alternatively, let me easily toggle your thread by subject line feature.

Thank you.

I'll write again.

Yours,

john
