Mate, please proofread your article. You are mentioning the pros of Optimistic roll-ups within the State channels section. Plus, sometimes you miss even the basic punctuation (e.g. Low gas fees Increased throughput Smart contract capability Security). I suppose you just copy-pasted but the bullet points haven't translated across.
I decided to read your article as it summarises the differences between different layer 2 scaling solutions. However, now I don't even know if you put text in the right sections.
