Letters and Reviews
lettersandreviews.blogspot.com
Free, personal curation site that aggregates **fund manager letters**, tickers mentioned in those letters, and **quarterly 13F** filer lists the author follows. Each quarter page links to original letters and maps tickers to quick‑reference pages; some 13F pages embed holdings tables and activity (new/increased/decreased/sold) for many managers. Also includes a small **Podcasts** list. No accounts, alerts, exports, or API—think link‑hub for primary sources rather than a data platform.
