woman hit and runs cyclist then brags on twitter

Yup.  This.  So many things are disturbing about that kind of lack of judgement.

The whole concept of twitter seems incredibly narcissistic.

I had a very interesting conversation with a group of community college students about FB and twitter.  I had no idea, really, how much time they spent on it and how much of a role it plays in their real or perceived "social capital".  It is completely bizarre.  I have been at a couple of graduation parties lately where groups of kids are sitting together but all on their phones.  I also often see groups walking on campus, all engaged with their phones. Sad:/

This has always been my thought about twitter.  It seems like a good tool if you want to disseminate important information to a large number of people quickly, but....what you had for lunch, a picture of your dog curled up sleeping or your opinion on Justin Beiber's latest hairstyle does not qualify as important information.

You people are all old and just don't understand today's youth.

^^^should be sarc font^^^

:)  I know you put it in sarc font, but at least in my case, it probably shouldn't be. 

I don't consider 39 "old" but when I talk to the 18-22 year old crowd now, I really feel a difference in age, a difference I didn't feel just five years ago.  I attribute a lot of that to the FB, twitter and texting phenomenons.  I hate talking on the phone, so texting has been an absolutely revolutionary thing in my life--I love it.  But I came to texting after growing up with real people skills, which very few young people I meet seem to have. 

I know I sound like a curmudgeon, but eye contact, a firm handshake and the ability to do participate in both the asking and answering components of general conversation, should not fall by the wayside.

The group of kids going out together but not interacting and always having their phone in hand makes me think that things are really not going to be OK.  When people spend more time staging having fun for twitter and FB posts than actually doing fun things and just experiencing them, and the inevitable need for validation of "fun" by your "followers" or "friends" that gets perpetuated, it has got to have far reaching consequences on their psyche. 

Now we have a whole generation of people like that. Yikes.

I didn't think of it as an either or thing.  To me it is very interesting that anyone would tweet something like that.

I think we can all agree that hitting a cyclist is effed up.  I think about it every time I get on my bike, and, unfortunately, we can't string together too many days without hearing about it happening.:/ But to tweet about hitting a cyclist, and to tweet about it with pride and disdain for cycling seems like an important part of the story to me, and it is a reflection of a certain type of culture that seems drawn to things l like tweeting.

Strava and BT are my Facebook and Twitter.

Just sayin'   

To the original topic, though: WTF?  I might be old fashioned at the ripe old age of 44 (OK, 45 by USAT - yes!!), but hitting a cyclist with a car should be a big deal.

Looks like she apologized....

... for tweeting about it.

You sound like you know the law regrading car v cycle aggression in the UK.  Why a "summons," and what exactly does that mean?
