In academic circles, we commonly say LGBTQ. The Women's Center on my current campus, which is also the LGBTQ center but they wont' relabel it, has a sign that says "GLBTQ", after which someone has penciled in an I. When I was at Indiana University about 15 years ago, student activists typically used the abbreviation LGBTQQPPIIAA.
The challenge is that, these days, we want to mean, in essence, "not straight" but without defining ourselves via the heteropatriarchy or in terms of negation. And that is going to be challenging. I would say that there are even heterosexual people who are queer--the poly and kink communities, for instances, both contain straight people and are certainly queer.
On which point, in academic circles, we commonly use the umbrella term of "queer", even more so than LGBTQ. But I've found that, in large, nonacademic circles, the word "queer" is considered hugely problematic for certain geographies and generations.
ETA: Sorry, didn't notice the poll.
