I don’t have any advice regarding your question, but I wanted to share something I’ve learned: people are very resistant to reading long paragraphs (and sentences for that matter). Splitting your post into multiple paragraphs would probably inspire more people to read you post, resulting in more or better feedback.
One thing to keep in mind regarding the charedi/dati leumi decision is that the dati leumi community is very diverse, including very nationalistic people and very moderate people, very MO people and pretty charedi people (chardalim), with everything in between.
Regardless, hatzlachah with your decision! 🙂
