I have a few more, but I don't want to spam. I guess I should setup a blog for this.

#42Single sender email addresses -- The idea is that a subscriber to the service gives out a separate email address to each friend or associate that he's willing to hear from (maybe from serialized business cards or whatever). The mail server accepts and records the first sender to any previously unused address, and subsequently performs a policy dependent action (e.g., blocking) when mail to that address is received fr…
I do something like this manually in my personal life.
It works good for memberships or online shopping; you have something like amazon.orders@your.domain, zappos.orders@your.domain, etc.
In real life not so much: people know they're getting a "fake" email address (regardless of whatever scheme you pick) and get put off by this.

#431. An URL shortening service for online stores. Online stores embed some JS into their store templates. Every page that displays a product now has an option to "share this product" (sort of like the UserVoice/GetSatisfaction "Feedback" tab). Clicking the tab/button gives the visitor a short URL for the product and options to share on Twitter/Facebook. Charge based on number of products. I actually think this could work (1 big customer and you're ramen profitable). If anyone is interested in teaming up on it, let me know.
2. A small .5-2TB hard drive or SSD array with a small cable. At the end of the cable is a memory-card shaped connector. The drive attaches to your digital camera's via the tripod screw. The cable goes into your memory card slot. Device acts like a high-capacity memory card. Perhaps even works as a RAID to prevent corruption.

#44Someday I want to make websites to run experiments on subliminal perception.

#46Earlier quoted context omitted.
What if the friend you gave the card to has several email addresses? Or changes his address and tries to email you from the new one?
Bayesean filtering? If it's trained on a corpus of mail from the same person, it could be more effective than in the general case.
Until they forward you a mail.

#47I think there's some good new communication tools around at the moment but it's an area I think that's difficult to monetize. (Facebook and Twitter IMO will have to look at something in addition to advertising.)
I would say there's plenty of opportunities for online marketplaces.
Internet growth in Asia right now, and potentially Africa in the future, will open up tonnes and the need to exchange goods and services.
Developing economies will want the same consumer goods as we do, and offcourse the enterprise will need the tools in order to provide these.

#48A version of social discussion site optimized for continuous discussion around a topic. One of my biggest complaints about HN is that it is very reactionary and every discussion ends in 24-48 hours. One of the reasons we have less "Hacker News" is that we've exhausted superficial discussions of a lot of topics and don't have a way to go more in-depth. I have some ideas about how to implement this but I don't want to…
Along the same lines--a wiki that contains all documented arguments and counterarguments on a given topic instead of rehashing them all the time over and over again on social discussion sites.

#49A small device embedded in a car's dashboard that monitors events such as:
- Anti-lock brakes or traction control kicking in (slippery road conditions)
- Drastic changes in temperature/humidity (potential for ice, fog, or whatever)
- Current speed (traffic flow)
and uploads this data, along with GPS coordinates, to a central server via cell phone data link or WiMax or something. Aggregate data about traffic speed and weather conditions nearby could be sent out to subscribers for display on an in-dash device:
"Hey, I see that 1.3 miles ahead on Hwy 494 three cars reported traction control kicking in within the last 20 minutes. Be careful!"
Getting manufacturers' cooperation for hooking into the cars' computers would be really tough. But the technology is perfectly feasible.

#50A realistic yet inexpensive robot hand that can curl its fingers in response to a remote wearer (wearing a glove). Would enable physical handshakes over the internet. And probably other things as well, people being as creative as they are...
That would be perfect for when somebody contacts you by email about millions of dollars to share. Once there's a real physical handshake, they would have no way to back out of that deal! Too much honor at stake!
