# /last30days v2.8
# /last30days v2.9
**The AI world reinvents itself every month. This skill keeps you current.** /last30days researches your topic across Reddit, X, YouTube, TikTok, Instagram, Hacker News, Polymarket, and the web from the last 30 days, finds what the community is actually upvoting, sharing, betting on, and saying on camera, and writes you a grounded narrative with real citations. Whether it's Seedance 2.0 access, paper.design prompts, or the latest Nano Banana Pro techniques, you'll know what people who are paying attention already know.
**New in v2.9 — ScrapeCreators Reddit + Top Comments + Smart Discovery:**
Reddit now runs on [ScrapeCreators](https://scrapecreators.com) by default — one `SCRAPECREATORS_API_KEY` covers Reddit, TikTok, and Instagram (3 sources, 1 key). Smart subreddit discovery finds the right communities automatically, and top comments are elevated with a 10% scoring weight and `💬` display with upvote counts. [Details below.](#whats-new-in-v29)
**New in v2.8 — Instagram Reels + ScrapeCreators:**
Instagram Reels is now the 8th signal source. TikTok and Instagram both run on [ScrapeCreators](https://scrapecreators.com) — one API key covers both. Search any topic and get trending Reels with views, likes, spoken-word transcripts, and hashtags. [Details below.](#whats-new-in-v28)

## What's New in v2.9
### ScrapeCreators Reddit as default
Reddit now runs on [ScrapeCreators](https://scrapecreators.com) by default. One `SCRAPECREATORS_API_KEY` powers Reddit, TikTok, and Instagram — three sources, one key. No more `OPENAI_API_KEY` required for Reddit search.
```bash
echo 'SCRAPECREATORS_API_KEY=your_key_here' >> ~/.config/last30days/.env
```
### Smart subreddit discovery
Subreddit discovery now uses relevance-weighted scoring instead of pure frequency count. Each candidate subreddit is scored by `frequency × recency × topic-word match`, and a `UTILITY_SUBS` blocklist filters noise subreddits (r/tipofmytongue, r/whatisthisthing, etc.).
| Topic | Before (v2.8) | After (v2.9) |
|-------|---------------|--------------|
| Claude Code skills | Generic programming subs | r/ClaudeAI, r/ClaudeCode, r/openclaw |
| Kanye West | r/AskReddit, r/OutOfTheLoop | r/hiphopheads, r/Kanye, r/NFCWestMemeWar |
| Nano Banana Pro | r/techsupport, r/whatisthisthing | r/GeminiAI, r/nanobanana2pro, r/macbookpro |
### Top comments elevated
Top comments now carry a 10% weight in the engagement scoring formula and are displayed prominently with `💬` and upvote counts:
```
**R1** (score:80) r/ClaudeAI (2026-02-28) [666pts, 63cmt]
Claude Code creator: In the next version, introducing two new skills
💬 Top comment (245 pts): "This is going to change how everyone works with Claude"
```
**Updated scoring formula:** `0.50 × log1p(score) + 0.35 × log1p(comments) + 0.05 × (ratio×10) + 0.10 × log1p(top_comment_score)` (was 0.55/0.40/0.05).
