right now, my portfolio is worth what someone is willing to pay for it.
is it for sale?
no.
am I developing?
yes.
that's where the real value lies.
what will a developed .mobi be worth... as compared to a parked or dormant .mobi?
imho, much more.
the important question is:
so, what is my portfolio worth to Me? my family? Our future? The answer is determined by how much I am willing to put into development in order to build true value through monetization, cross-marketing/sales, traffic-flow to my "PC" sites, extended mobile services for my PC sites, etc...
if some of you believe your domains will be worth $100 EACH, OR $1,000s each (or more), won't development of those domains over the next 5 years (even simplified development using free tools out there) help that goal be realized and add a better foundation to what those domains are worth?
i.e.
I own Single.mobi - bought it around Christmas 2006.
The premium (held by mtld) domain: Singles.mobi sold for $40,000+ at recent TRAFFIC live auction. Does that instantly make my domain "worth" anywhere near that amount? Yes, No, Maybe, Maybe not.
But when I develop it into a social network that allows users to network, connect, meet, track, locate, message, etc and if I can build the userbase to even 1,000 members by this time next year and give those members all the viral tools they need to promote the site, will my domain have a better chance of being worth $40,000? Of course. What if I have 100,000+/- members within 3 years? What is that domain/site now worth? I hope many .mobi owners realize that you need to DEVELOP DEVELOP DEVELOP... that is key... unless you have an AMAZING portfolio that sells itself, we can all have a serious impact on the .mobi universe/ecosystem if we choose to develop even 1 domain in our portfolio.
if you're reading this and don't agree that DEVELOPMENT is important, just imagine what happens to the value of your .mobi portfolio is NO ONE CARES, if there are no .mobi sites out there for users to find/enjoy... what is your domain worth if that happens? you can sit back and wait&see or be proactive and spend 1 hour of your time each week (or day) and build a new site or put more time into an existing site.
if some of you are lost on how to begin development, look thru your own portfolios and find the EASIEST site to build that you can get content for and/or provide content on your own. then go to MTLD's site and find links to all the tools they've made available. if you don't have any domains that can work for development, then might I suggest you register a local city name in your area and build a local directory. you can find ways to monetize later (by charging businesses, etc) but the content is easy to build and add to.
i.e.
if you live in MIAMI
go register 1 of the following:
miami.mobi
miamiINFO.mobi
miamiGUIDE.mobi
miamiSAVINGS.mobi
miamiREALESTATE.mobi
miamietcetcetcetc.mobi
etc... you get the idea.
you don't need them all... just by 1... and yes i know Miami is gone, but just target your city, or a local one and add some content, then contact a few newspapers, tv stations, etc, and see if they want to do a quick story on what you're working on... you never know. submit to a few search engines, place a classified ad, whatever it takes to drum up traffic.
plus deep inside, I know most people will just sit back and park their names and wait for a big payday to fall into their laps. Too many domainers look at their domains as lottery tickets.
ok, my rant is over.

time for lunch.
good luck to everyone.
also, if you're looking for cheaper .mobis, godaddy has a coupon code for 2 .mobis FOR $20: gdm0236d (at checkout) - don't know how long it lasts (everywhere else is back to about $15 each).
