Your clothes and a tape-measure are your best indication. Since you see yourself every day, it's hard to see any difference. Same with other people who see you on a regular basis, or family, who've seen you at a variety of weights, and you only see every so often.
Also, the heavier you are, the harder it is for people to see a big change until you get closer to your goal. Seeing as you started at 260 and are now down to 244 or so, I'd say give it another 10-15 lbs. When I used to weigh 250 (7 years ago), nobody started making comments until I was down to about 210. :-P Really, you can't rely on other people, because even if they do notice, they might not say anything, because (being larger) they assume we're self-conscious about our weight, and don't want to draw attention to it (good or bad). I did get all the way down to 175, which was great, and while nobody really commented on how much I'd lost, signs indicated I looked good whether people knew I lost anything or not! ;-)
Alas, after keeping it off for 5 years, I moved, couldn't find a gym I liked, got a job that keeps me chained to the desk, finished one degree and started on another. I know, excuses, but it was enough of a time/convenience factor that I let a lot of it come back. *sigh*
This time around, I notice changes (in myself) because I have a memory of skinny-me to compare it to. The most noticeable is that I've got horizontal lines across my belly where I've lost fat, but the skin's stretched out - ew! Owell... it'll catch up... but this is another motivational reason to keep it off once you get to your goal. Once I had made my goal-weight, I still looked kinda "pudgy" to myself. I didn't really start looking fit/skinny (to me) until a year or so after, because by then, all the skin had stretched back, I had some color, because I was doing a lot more outdoor activities, hiking, swimming, etc., I looked healthy and fit, I'd replaced my wardrobe with smaller, non-baggy (& more flattering) clothes, and I wasn't used to looking for the flaws any more, because I was at a good weight.
So... I guess the lesson is, keep it up, and you'll see changes, and so will everyone else! And once you get there, keep it up and keep it off!
