Show HN: Ask questions that the social media Zeitgeist will answer (opens in new tab)

Hi HN,

I'm building a tool that let's you ask questions that the social media Zeitgeist--with focus on investing--will answer.

Examples:

Question: Is the S&P 500 going to rise or fall in 2023? Answer:

> The comments have mixed opinions about whether the S&P 500 will rise or fall in 2023. Some predict a drop in the first quarter of 2023, while others believe it will rebound and end the year higher than it is now. The average forecast expects the S&P 500 to end 2023 at 4,009, but the predictions range from a low of 3,400 to as high as 4,500. Overall sentiment remains bullish on the stock market despite some downside risks.

Question: Is it a good idea to DCA in the S&P 500? Answer:

> The comments are mixed, but the majority of them suggest that DCA (Dollar Cost Averaging) into the S&P 500 is a good strategy for long-term investment. Some comments suggest waiting for the market to drop further before starting to DCA, while others suggest starting immediately. Some comments also mention the importance of considering the volatility of individual stocks and the benefits of investing in low-cost index funds. Overall, the comments suggest that DCA into the S&P 500 is a safe and effective investment strategy for most people.

Question: Who profits from the war in Ukraine? Answer:

> The comments suggest that the US is profiting from the war in Ukraine through its military-industrial complex and arms sales. Some comments also mention that the war is hurting the world economy and that Russia is allegedly providing material support to prolong the conflict. There are also comments that suggest both Ukraine and Russia are profiting from the war.
