The 2-Hour Rule: Why Reddit Replies After 2 Hours Don't Convert
By hour 2, the top comment owns the thread. Mentionly pings you within 5-10 minutes so you can be the top comment.
The problem
Reddit threads are won in the first 2 hours. After that, the top comment has 5x the upvotes of comment #2, and the OP has usually clicked away to whatever the top comment recommended. If your reply lands at hour 4, you're talking to nobody.
Manual scanning can't beat the 2-hour rule. By the time you check r/SaaS during your lunch break, the top thread of the day is 6 hours old. Mentionly closes the gap with 5-10 minute alerts.
How Mentionly solves it
1
5-10 minute alerts the moment a match lands.
2
Push notifications + email + Slack so you don't miss it.
3
Triage UI: mark replied, dismiss, save — so you only see what's still actionable.

Frequently asked questions
What if I'm not at my desk?
Slack/Telegram alerts work on phone. The 2-hour rule is forgiving — it's not the 30-minute rule. You have time.
What if the thread already has 5+ comments?
Skip it. The cost-benefit drops off fast. Move to the next match.
