Hmm...it's quite interesting to here this from a woman's point of view.
The flakiness factor and inability to make real friends and establish real relationships in SD is something that has been brought up on this board time and time again, usually from men, so it's refreshing to hear the same frustration from a woman this time.
Here's just one of many that I've seen...

And lately it's just been like deja vu over and over again whenever I see a new post on the board. And just like you and others have already mentioned you also get the same story from real life people we meet out in the real world and not just behind a computer. They all say the same thing, transplants and locals alike, the general consensus from all of them is SD people can tend to be a tad bit flakey; it's pretty much a fact.
I think it's more of a cultural thing than a personal thing. I mean what can you say it's Cali, it's SoCal, it's Hollywood, it's Californication, etc...etc which may translate to an I'm "too cool for school attitude" and my time is more important than yours and I don't need to take the extra step to make friends but you do because you're newer than me and I'll still flake on you if I feel like it. I know it's quite funny but also somewhat sadly true. Hey, I guess it's just one of those things that come with the territory of living here and now at least you're aware of it. Not everyone can see this or is willing to admit it but at least you do.
Some successful transplants have told me that it takes time. Apparently the general consensus is 3 years. But what really confuses me is when I hear these same frustrations from native San Diegans who have lived here there whole lives. So again maybe it's not just a time issue but a cultural issue as well. I dunno, I guess only time will tell.
As far as the meetup group advice, boy has that site been getting free publicity or what!?, I mean don't get me wrong, I'm all for positive advice but I wonder how many people in other cities like Boston or San Fran need to use the internet and meetup groups to make friends. I think if you have to do that in San Diego then that might be proof that there's a problem.
It's expected that some people, specifically in a forum setting like this, will get overly defensive and protective about things, especially if they really like their city and its citizens and they take it personal because they feel like they're being criticized. Anyway, it's funny how they will get offended by labeling SD as flakey and yet at the same time advise you that you need to avoid the 20-30 age range all together because they're all flakey. Can someone say "Irony"?
In conclusion not all SD people are flakes obviously; I see many friendships and group activities here all the time. In fact if anything it's somewhat cliquish. I guess it's just gonna take you some time to find your comfort group but at least you're aware of the task that's ahead of you which I'm guessing is something you weren't privy to coming in, the taking classes or doing things that interest you advice sounds like a good one. Or you could just email the guy who started the earlier thread. Seems like you guys have something in common and he's also in your age group.
Or, you could email the person who wrote this post, *Hint* He's in your age group too

Oh and don't worry I wont insist on having my turn with you, unless you really want me too

No but seriously I could use a good wing woman

I know...I know "Irony"
