I'll give you my experience with it as a 20 year old 2nd year college student for reference.
I frankly think it's impossible to DJ through text messages and I in fact think that setting up a date through a text message is a wimpy thing to do. In fact I had one girl tell me earlier this year that she thought text messaging was "weak" from a guy, because if he takes the time to type a message he should just call her! This is funny however as I ended up getting involved with this girl later on and all she does is text message me!
Now I'm new to this, I just got a new cell phone in March with texting capabilities as my old one didn't have it. So anyway, I ended up getting this girls number, and I proceeded to call her and set up dates as I usually do and we went out twice. But then she started text messaging me. Now I didn't know how to handle this as it was new, so I usually replied to them. She would send them once or twice a week. I never once asked her out through the text messanger but she would invite me out through it! lol. I guess she thinks it's weak for guys to use but she will use it to set up a date! Anyway, at some point she began texting me every single night, sometimes 2 or 3 times! Being uneducated in this new form of communication I usually replied to most of them. This was a mistake! Even though I did not initiate any of these text messages I gave her to much attention by always replying, and it also showed her in a subconcious way that I had nothing better to do but reply to these ridiculous messages. So when I called for a date at the end of the week, she completely flaked out and made up some lame excuse! What went wrong I thought? Well I gave her to much attention, she got all that she wanted and now she had enough. So I got some help from this board here and decided to cut off all contact. After 4 days of no contact she texted me and I didn't reply. Again, and I still didn't reply. A week after contact was seperated she hunted me down at school and asked if I had been getting her messages. I just said yep, and kept talking with my friend lol
The texting continued and I just stopped replying, it drove her crazy, she actually called me and asked if I wanted to meet her somewhere at this point! At last, I defeated the texting game, or so I thought. After I met her she was really friendly and touchy feely, and then the texting began again. Except this time I was smarter, I just never replied unless it was an actual question that requires an answer. All these cute/stupid little message just collect on my phone, she has asked me out through text messenger 3 or 4 times as of now. Once was a "demand" of sorts in which my reply was a phone call where I changed the meeting to a time 3 hours later and she actually said, "well whatever time fits your schedule better". Now that's more like it!!!!
As of today I have 19 text messages on my phone in one weeks time. 1 is from my friend 18 are from this girl lol! I have replied to a grand total of 2! Of course now I have a real date set up again with this girl, she actually suggested it in person because now she is desperate it seems. I will set up the time and place via the REAL phone. Mind you I have another girl in my situation as this one is just to damn flaky, and girl #1 here actually knows about girl number 2 so that helps my situation! Btw Girl number 2 never, ever uses SMS so go figure? lol.
So my experience has tought me a lot. Only set up dates through the phone! Even if you do this already don't get caught up in replying to all those cutesy stupid little messages IGNORE THEM! Rarely if ever send a text unless it is really important, or if you already know the girl I see no harm in sending an amusing little message every now and then and I mean only once in a great while here! Texting seems to be the attention wh0re's new format for playing mind games, don't play it or they win.
So that's my 2 cents .
