Show HN: Track product alternative requests on Reddit to find product ideas

I often browse through subreddits like r/iosapps, r/macapps to find product opportunities & market gaps.

I noticed a pattern: users frequently ask for alternatives to existing tools when they're frustrated with current solutions.

These posts are a great source of inspiration for product ideas as users are actively searching for alternatives to products that they already use & they describe their pain points with the the current solution.

So I build a free tool, AlternativeWatch.com to collect & curate such posts.

What it does: - Monitors product-focused subreddits for "alternative to X" posts - Displays live feed of recent alternative requests - Lets you browse historical data of past requests - Sends curated opportunities twice a week via email

Looking for feedback on: - Which additional subreddits would be valuable to monitor? - Better ways to categorize & enrich the opportunities - What other data sources can I use to add more value?
