I'm enjoying reading what others thought about the day, so I thought I'd jot my thoughts down too.
First of all, it was bloody great to meet the other MNers who were there. Really that was the highlight of the day for me
I feel I should publicise the fact that a bunch of us LITERALLY told Sandi Toksvig how to find the toilets
But anyway, yeah, Sandi's (yeah, first name terms 
) speech as part of the opening session was entertaining, as you'd expect, but the stuff about male brains and female brains made me go 
. But I liked the stuff about the cotton gin having been invented by a woman (but a man got the credit because women weren't allowed to register patents), and the bit at the end about Khutulun, Kublai Khan's niece. I'm continually amazed by the way women have been erased from history, so it was cool that ST highlighted a couple of remarkable women I'd never heard of.
The morning seminar I went to was "'Our strength, our space': the importance of women-only organising" run by Julia Long from LFN. Apart from the fact that the room was too small, so many of us had to sit on the floor and I'm too old and creaky for that shit - my arse felt like it was on fire by the end of it - this was a brilliant workshop. There was one contribution in particular that has stayed with me: a woman who works in mental health services in Liverpool who spoke about how she had set up a women-only group for MH service users, how successful this group had been, and the lack of support from management for it such that she felt they were almost having to run the group in secret. That struck a chord with me and many others in the room, I think; how difficult it has become to create and protect women-only spaces without 'what about teh menz' complaints. Tbh this workshop could easily have gone on all day: it felt like we were scratching the surface really, but the energy in the room was great and - as SaF said upthread - there was a mix of ages there that could have led to some fruitful intergenerational discussion, and brought home to me the importance of intergenerational exchange and activism, which often appears to be dominated by very young women.
After lunch I went to the Object seminar in the big hall. The presentation included some excellent videos of Object's activism and a hilarious BBC News TV interview in which Anna from Object wiped the floor with an appalling bloke in a discussion about lad mags. The list of Object's campaigns and successes was truly impressive: how they've changed the way lapdancing clubs are licenced and the change in the law criminalizing punters who use prostituted women who have been trafficked or coerced (although AFAIK this law hasn't led to any prosecutions yet). When they opened the floor for questions though it became clear that the audience was split with almost half of the audience seeming hostile to Object's position on prostitution (supporting the Nordic model), lap dancing and porn, and those who asked questions like "why shouldn't women be lap dancers if they chooooooose to do it?" got a bit bolshie about the responses from the panel, didn't really listen to the answers and spent the rest of the seminar muttering audibly. I found this slightly surprising because I thought there'd be more division in the room at the women-only organising seminar, and didn't expect such a large contingent of hostile funfems at the Object one.
The feminist question time session was excellent, I thought, especially Bea Campbell who made some interesting points: for example, on the subject of porn, she questioned the sharp divide in attitudes towards pornography depicting children (universally accepted as harmful) and that depicting adult women (rarely accepted as harmful). I found Zoe Williams disappointing and like QoABaM I thought her flippant remark about tories was annoying. She also took a cheap shot at Lynne Featherstone: and yes, OK, LF can rightly be criticised, but it felt completely inappropriate to pick on her in that way at a feminist conference. Regarding the bloke from the anti-porn men project on the panel: I felt a bit hostile towards him a) because we'd already had another bloke from the anti-porn men project on the panel in the opening session (who was crap); and b) why do we need blokes on these panels at all at a feminist conference, as if they don't get enough opportunities to speak the rest of the bloody time. The star of the show for me was Carlene Firmin though. I'd never heard of her before but she kicked arse on that panel: I loved the way she used the word misogyny without apology.
I bunked off after that session thinking that the mayoral hustings would be boring, but from what I heard it was pretty good.
Overall, an excellent day that far exceeded my expectations.
