You can expand the long text cells by clicking the expansion arrows that appear in the top right corner of the cell. I would also highly recommend using the full-screen version rather than embed (by clicking "View Larger Version"): https://airtable.com/shrOQ3Gf4Hs3Gvvvc
I would also add that, while I'm certainly biased, there is benefit to making this a "cloneable" database that you can then use as a personal checklist, add notes, further attachments, etc which you wouldn't be able to do with a simple blog post, for instance.
For starters,
1) File attachments
2) Better mobile UI (Airtable's database records can be displayed as cards on touch devices, whereas a traditional spreadsheet is always a 2d grid).
3) Interactive fields like checkboxes, dropdowns, etc.
4) Ability to expand records into a form detail view for better readability of long text, etc.
