Check out http://bitcoin.meetup.com/ to see if there are any groups in your area.

Then check out LocalBitcoins.com for people buying/selling in your area.

Reach out to all of them and see if they are interested in meeting up on Bitcoin Wednesday.

When you get a meeting going, it's just socializing. We talk about the latest bitcoin news, projects we're working on, or more general stuff like politics, etc.
Try and get a poster board and easel to put on your table or near your gathering spot so others around you know what you're doing - it helps awareness and you'll be surprised how many "outsiders" inquire and have "heard something about it" and want to  know more.

Then when you get brave and motivated enough, you can entice merchants with your growing numbers and ask them to accept bitcoin in return for your patronage.

It's GREAT fun!

Join what? A particular event, or start your own event?

Las Vegas checking in. Today at noon.

Dunno if this is it, but if the coins you're spending are newly generated and have not yet received 120 confirmations, you will get this message.

Doesn't quite have the same sound as silver on silver. I will probably just have to "launder" some bitcoins off the silver and into my offline wallet on the coins I want to tinker with.

Any way to buy the 1 ounce silver as blanks?

I am addicted to carrying some silver around in my pocket every day and the holograms won't last.

I'm getting this message too and it appears to be related to newly generated bitcoins. Some of the inputs I'm trying to spend are not quite old enough (confirmations). I'll come back and confirm this in a few more hours sometime after I receive 120 confirmations. I'm at about 50 right now.

I'm starting to smell a scam... why wouldn't they just keep all the hash grease for their own cables to rake in all the slippy bits for themselves?

Does this make Monster Cables (tm) work any faster too?

Nice work SgtSpike.

I don't have any power data, but my 4 Jalepenos are putting out 22GH/s.

Difficulty is recalculated every 2016 blocks regardless of the time it took to make them. It's *suppose* to be 2 weeks, but in the context of some cryptographic super horsepower device that can do googolhashing, it only lasts a very short while. only about 8000 blocks can be generated in a short time before it goes back to 10 minute blocks at that hash power.

Pretty sure this would result in a unanimous consensus to roll back the blockchain and instantly invalidate those billions of dollars spend on the hardware.

Need this in Vegas!

That sounds about right. The difficulty and reward values are all calculations based on each client's perception of data in the blockchain. Because they all follow the same rules of interpretation, they all come up with the same changes to reward and difficulty that must then be used later on.
