Is it weird to text about something from her profile

When someone writes something in their profile, they're telling you what they want to talk about. If she mentions hiking or coffee or that she's bad at cooking, she's given you permission to go there. She's not expecting you to pretend you didn't read it.

The signal that matters is whether what she wrote sounds like a real fact about her or just a generic template she filled in. 'Hiking' is generic. 'I get weirdly competitive on day hikes and have a spreadsheet' is real. Reference the real part. That's where the conversation lives.

A good profile reference does two things at once. First, it proves you read her actual profile and you noticed something that matters to her. Second, it says something about you or asks something real. Don't just repeat back what she said.

If she wrote about cooking, don't say 'I see you're bad at cooking.' Say something that puts you in the picture or asks her something you actually want to know. Mention a specific experience of your own that connects, or ask a question that only makes sense if you actually care about her answer.

Reference her profile in your first or second message. That's when it's fresh and it does the job it's supposed to do, which is starting a real conversation.

Don't save a profile reference for later when she stops replying. That reads as desperate and it makes her profile detail feel like an excuse instead of a real opening. If she's gone quiet, a profile callback won't fix it. Move on instead. If she does reply to your first message and the conversation stalls three or four exchanges in, don't suddenly reference something from her bio. That looks like you're running out of ideas.
