I just read this post and many of the comments yesterday, then today I was reading a story, and -- two-way wormhole! *sigh* And really, there was absolutely no reason to go against canon that way, the desired function could have been achieved through some other device. That the wormhole goes only one-way is such a huge and often employed plot contrivance in the Stargate universe, going all the way back to the movie, it really seemed as bad as suddenly making a character switch gender w/o explanation. *headdesk*

And I'm asking myself if I would have had such an extreme reaction if I hadn't just read this post... ;)
