i've always thought that the critical analysis forum was for "critical analysis," lol, a place for in-depth comments on why and how a poem works (or doesn't work) and for offering honest opinions and suggestions for improvements. true, alot of people post comments on poems in C/A on the order of "i loved this" or "this was beautiful and heart-felt" without giving the poet any idea WHY the reader loved it or thought it was beautiful, but that's always going to happen. not everyone feels they are able to critique a poem (although it has always puzzled me why anyone who loves writing can't engage in a little introspection and come up with some reason WHY they liked a poem, but that's another thing entirely, lol), but that shouldn't deter you from offering your own opinions and suggestions in a forum called "critical analysis."
it sounds, jp, like you had some bad experience in C/A, where perhaps someone got upset with your critique. well, that happens, i guess. like elizabeth says, not everyone WANTS their poem critiqued. i think you have to assume, however, that, given the choice of forums at the site here, anyone who chooses to post a poem in "critical analysis" (rather than the open forum, the corner pub, or any of the other forums) does, in fact, want a critique, something that goes a little further than "nice work, i enjoyed this," and you should feel free to post a honest critique, positive or negative or whatever. after all, that's the whole point of a forum called "critical analysis," lol. they may not like what you have to say, lol, but as long as your critique is honest, courteous, respectful, you should have nothing to worry about. being constructive, too, is, as sunshine says, always nice. if someone gets upset with an honest, courteous, respectful and constructive critique, well... there ain't nothin' you can do about that.
i absolutely love the critical analysis forum, and i hardly post in any of the other forums any more. sure, i've had my ego bruised there plenty of times, but reading the detailed responses not only to my poems but to the poems of others, too, has really helped me as a writer. granted, it's not for everyone, but i wish more people, especially the regulars of the "open" forum, would drop on by from time to time and get involved in C/A's never-ending discussion of this most difficult and challenging art form.
